JPanel highlight cells in a grid

i would like to know how to highlight a particular cell when a user clicks on it?
Basically i have code to choose a specific cell but i dont know how to highlight them(like a border highlight, much like in Ms excel)

nono, im creating a game and i have a jpanel with a grid drawn on it.
basically i just want to highlight a cell i click....hope that makes senseIn that case you'll have to do it manually. Keep track of which cell was clicked, and draw the border around that cell. You ought to look into whether you could replace your grid with a JTable though, it provides things like that for you.

HOW TO GET VALUE OF A PARTICULAR CELL IN ALV GRID

I HAVE 2 ALV GRID. IWANT WHEN I DOUBLE CLICK ON ANY PARTICULAR CELL OF FIRST GRID I WILL GET THE VALUE DISPLAYED ON THAT PARTICULAR CELL.
THANKS IN ADVANCE

Hi,
If you are using a class alv, you only need to create a local class to control event and, before setting the screen to present the alv, you need to assign the class as a handler, like this:
    CREATE OBJECT event_handler.
    SET HANDLER event_handler->double_click FOR alv_grid.
This event handler was defined before like below and a object was created for it:
CLASS cl_event_handler DEFINITION.
PUBLIC SECTION.
    METHODS double_click FOR EVENT double_click OF cl_gui_alv_grid
      IMPORTING e_row e_column.
ENDCLASS.                    "cl_event_handler DEFINITION
Then you need to implement this class, creating the method double click and do a READ TABLE to the itab you presented in the alv to recover the data, like this:
    READ TABLE itab INTO wk_itab
      INDEX e_row-index.
The e_row structure was sent to the method by the handler, setting it with the line index that you double clicked in the alv. After that, you can manipulate the data that you selected in your internal table to generate the data to the other ALV.

Referencing cells in a grid layout

I am adding an extended component to a container with a GridLayout, in this case a 10x10 grid. Is it possible to reference an individual cell of the grid?

Why would you want to "reference" a particular cell in the grid? Wouldn't you just access the component in the cell?
If you're really trying to add negative (empty) space in your grid, you should use a GridBagLayout instead. You get much more control over the layout, particularly when you're dealing with a resizable frame.

Possible to have vertical scroll bar for a cell in ALV Grid (using methods)

Hi All,
I have a field with length 100 characters on a ALV Grid (using methods)..User doesn't want to scroll all the 100 characters horizontally to see the whole text rather he wants to have a vertical scroll bar for the cell so that he can scroll vertically.
Is it possible to have split the cell text into lines and have a vertical scroll bar for a cell in ALV Grid?
Regards
Jaker.

Thanks for the suggestion Balu.I tried this , but while scrolling,headers also getting scrolled.
Becoz of this , if i scroll down to the last row,headers are getting hidden.
Headers should always be static.only the data should scroll.
Since h:datatable is being rendered as one table , i can div tag for this table alone.
If i have seperate datatable for headers alone i can do this .But i should not use two datatables.

Display only cell in ALV Grid in OO

Hi Folks,
Hope someone can help me with this little issue. I have a series of columns in my ALV grid that are editable, but I need to a) make some of the cells on specific lines uneditable and b) display time based fields on this line as blank (presently they shoe 00:00:00).
For problem a) I have set the layout style frame as 'cellstyles'
    es_layout-stylefname = 'CELLSTYLES'.
I have also set the edit flag in the field catalog for the individual columns to 'X' eg
     WHEN 'CUSTTS_DATE_N'.
          ls_fieldcat-edit = 'X'.
And coded:
       gwa_stylerow-fieldname = 'CUSTTS_DATE_N'.
      gwa_stylerow-style = cl_gui_alv_grid=>mc_style_disabled.
      APPEND gwa_stylerow TO gt_stylerow.
      wa_delivery_list-cellstyle[] = gt_stylerow[].
      APPEND wa_delivery_list TO it_delivery_list.
Yet, the ALV cells are still being displayed as editable. Can't for the life of me figure out what's missing. The only other thought I had around this is that the wa_delivery_list-cellstyle table is being set in the data extraction code, before the ALV grid is built, and that the cell formats are being overwritten/on not being called by the field catalog entries. Any thoughts on how to make these fields/cells display only when the ALV is first displayed would be greatly appreciated.
As for option b) I'm clueless, as the cell style commands are not being picked up (see problem a.). Again any thoughts would be appreciated, and points will be rewarded for solutions/suggestions that lead to solutions.
Cheers,
Stephen Keam

How to diable a cell in SAPbouiCom Grid

Hi All,
Is it possible to disable a cell in SAPbouiCom.Grid ?
Now, I'm binding the data to gird with the datatable as follow.
Me.grdData.DataTable = Me.oSAPForeCast ' oSAPForeCast is SAPbouiCOM.DataTable
Any ideas?
Thanks,
Lei

Hi Nandar,
If you want to disable an entire column, use Pari code.
If you want to disable a single cell, you need to catch that cell's click event and change the focus to another cell (I usually use oApplication.SendKeys("") to simulate a Tab pressed).

Obtaining a cell within a grid

Hi all
I wish to obtain the cell within a grid on which the user has clicked in order to obtain its value.
question is how can i obtain the cell by code?
appreciate the help
Yoav

Hi!
You wont be able to get the specific cell, you will have to get the value from the datatable behind the Grid. It is a limitation, but that is the functionality the grid is actually offering.
Hope it helps;

How to set the cell size in grid layout where each cell is a panel

Hi,
I am using a grid layout where each cell is a panel. Here I want to
set size of each panel to be equal irrespective of any. But it is not obliging the setSize().
no of row in grid - 4
no of columns - 4
each cell is a panel. each panel has a label.
panel.setSize(parent.getWidth(), parent.getWidth()/4); // not working. Size is adjusting to the length of the label.
I want to force the size of the panel to our preferred size.
Note: In swing we can use JPanel.setPreferredSize(). Unfortunately I cannot use Swing components. Requirement is awt only.
Any help in this is highly appreciated.
Thanks
Kishore

I observed it is same behavior with gridbag layout. Infact it is gridbag layout only with 4 cells, where first cell should be of constant width (it is base for other cell widths) and other cells are variable (some integer*base width of first cell). I want to set the size of first cell width to be constant.
Though it is redundant I once again say that it works perfect with setPreferredSize of JComponent.
But I should not use any swing component/api. This is sytem requirement.
Any help is appreciated.
Thanks

OO ALV - How to highlight cell after value change

Hi All,
I have an OO ALV with an input enable column and would like to highlight a cell in a different color when the user changes it's value.
I am using pr_data_changed->get_cell_value to check the cells value has changed and pr_data_changed->modify_cell to update the cell with the new value.
The output table has a field called CELLCOLOR of type LVC_T_SCOL which I am using to highlight the cell in red:
         lw_cellcolor-fname = 'THISFIELD' .
         lw_cellcolor-color-col = '7'.
The ALV layout is also correclty set using:   layout-ctab_fname = 'CELLCOLOR'
All the above is working fine and the changed cell is highlighted HOWEVER it only works if I call METHOD g_grid->refresh_table_display
Is there anyway to highlight the cell without calling method refresh_table_display??????
I do not like to call method refresh_table_display in an ALV event. The main reason is if a user changes a cells value and at the same time selects the row for update then the method refresh_table_display wipes out the row selection marker.
So Is there anyway to highlight the cell without calling method refresh_table_display??????
All your help appreciated
Che

Try this way
In the PAI use
call method get_selected_rows
This will get you the row index of the selected rows from the screen for example I_ROW
In PBO
call method g_grid->set_selected_rows
exporting
it_row_no = i_rows[].
then call refresh_table_first_display
So this one will keep row selection after the refresh_table_first_display method

Using a JPanel as cell editor in JTable

I have a composite component (JPanel that contains a JTextField and a
JButton) that I would like to use as the a cell editor in a JTable.The JButton instantiates a UI editor component that I have designed. Example would be date editor for dates, tet editor for strings etc. This editor allows the user to select a date to populate the JTextField (the date may also be manually entered).
I have no problem with the rendering of the component within the table.However, I would like for the JTextField embedded within the JPanel to receive focus and a visible caret, when using the tab key to navigate to the cell. After reading through some of the posts here , I was able to transfer the focus. But I dont see a visible caret. I am unable to edit. I have to click on the text box and then start typing. Its a great pain in the ass.
I have a custom designed table and custom designed editor. Code is attached...
<pre>
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e,int condition, boolean pressed) {
final int selRow = getSelectedRow();
final int rowCount = getRowCount();
final int selCol = getSelectedColumn();
final EventObject obj = (EventObject) e;
if (selRow == -1) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
changeSelection(0, 1, false, false);
editCellAt(0, 1, obj);
boolean isSelected = false;
if ((ks == KeyStroke.getKeyStroke(KeyEvent.VK_TAB,0)) ||
(ks == KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0))) {
if (selCol == 1) {
isSelected= getCellEditor(selRow,selCol).stopCellEditing();
targetRow = (selRow + 1) % rowCount;
SwingUtilities.invokeLater(new Runnable() {
public void run() {
if (editCellAt(targetRow, 1, obj)) {
changeSelection(targetRow, 1, false, false);
getComponentAt(targetRow, 1).requestFocus();
} else {
getCellEditor(selRow, selCol).shouldSelectCell(obj);
return super.processKeyBinding(ks,e,condition,pressed);
</pre>
Relevant code of my custom editor is below....
public Component getTableCellEditorComponent(JTable table,
Object value, boolean isSelected, int row, int column) {
lastEditedRow = row;
lastEditedCol = column;
lastEditedTable = table;
lastEditedValue = value;
val = value;
((JTextField)editorComponent).
setText(val == null ? "" : val.toString());
setClickCountToStart(1);
if (value instanceof CycCollectionChooserModel) {
String collection = ((CycCollectionChooserModel)value).
getCollection().cyclify();
button.setVisible(EditorForCollectionMap.hasUIEditor(collection));
button.setMargin (new Insets (1,1,1,1));
button.setIconTextGap(0);
buttonListener.model = (CycCollectionChooserModel)value;
buttonListener.rowIndex = row;
buttonListener.localTable = table;
return panel;
public boolean isCellEditable(EventObject evt) {
if (evt instanceof MouseEvent) {
int clickCount;
clickCount = 1;
return ((MouseEvent)evt).getClickCount() >= clickCount;
return super.isCellEditable(evt);
public boolean stopCellEditing() {
if (super.stopCellEditing()) {
final int targetRow = (lastEditedRow+1)%lastEditedTable.getRowCount();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
lastEditedTable.changeSelection(targetRow, 1, false, false);
lastEditedTable.getComponentAt(targetRow, 1).requestFocus();
return true;
return false;
Does any one know why I am not able to see the caret? Any insights you have will be most welcome.
Thanks in advance,
Praveen.

Almost solved the problem. Navigation through Tab key, up/ down arrow, Enter key works for text boxes. Navigation through Tab Key, Up/down arrow works for combo boxes. But for "Enter" key it doesnt. Changes in code ....

Value of the previous cell when I double click a cell in ALV Grid.

Hi !
Suppose I have an internal table GT_ITAB and I use ALV Grid to print it on the screen. The colums are as below:
Invoice No Invoice Data Customer No Amount
90001231 15.01.2009 100024 5
Customer No Fields is Hot Spot and when I click it uses Call Transaction 'FD10N' and Skip First Screen.
But the Problem is that :
Callback subroutine that is defined for "i_callback_user_command" receives the input and
p_selfield type slis_selfield structure has the value by means of p_selfield-value.
Problem : How can I get also the value of Invoice Data Cell. I need "15.01.2009" to set the Year field of FD10n.
I know that it is possible because SAP has examples of it.
Please advice.
Erkan VAROL.

Hi ,
In teh structure slis_selfield there is a field tabindex , you can get the index of the record selected from this field and use this to read the internal table being displayed in the alv to get the entrired row.

How to highlight cell in a tree programatically when mouse arrow is moved over it

Hi
I would like to highlight a particular cell in a tree when a mouse arrow is moved over it. Similar to wndows drop down menu. Can anybody help me on these.
Regards
Bharath
Solved!
Go to Solution.

But I find an issue with this. When there are items with same values in the tree, it always points to the first matched value (even if I set the active item tag to the one where I want to point to). For example, if I have a tree with values "Hello, Hi, Bye, Hello" and then I set the value to "Hello", it points to the first "Hello" even if I set the tag to the second yellow. Do you know any easy work around for this? Thank you!

ABAP List Viewer
The common features of report are column alignment, sorting, filtering, subtotals, totals etc. To implement these, a lot of coding and logic is to be put. To avoid that we can use a concept called ABAP List Viewer (ALV).
This helps us to implement all the features mentioned very effectively.
Using ALV, We can have three types of reports:
1. Simple Report
2. Block Report
3. Hierarchical Sequential Report
There are some function modules which will enable to produce the above reports without much effort.
All the definitions of internal tables, structures and constants are declared in a type-pool called SLIS.
1. SIMPLE REPORT.
The important function modules are
a. Reuse_alv_list_display
b. Reuse_alv_fieldcatalog_merge
c. Reuse_alv_events_get
d. Reuse_alv_commentary_write
e. Reuse_alv_grid_display
A. REUSE_ALV_LIST_DISPLAY : This is the function module which prints the data.
The important parameters are :
I. Export :
i. I_callback_program : report id
ii. I_callback_pf_status_set : routine where a user can set his own pf status or change the functionality of the existing pf status iii. I_callback_user_command : routine where the function codes are handled iv. I_structure name : name of the dictionary table v. Is_layout : structure to set the layout of the report vi. It_fieldcat : internal table with the list of all fields and their attributes which are to be printed (this table can be populated automatically by the function module REUSE_ALV_FIELDCATALOG_MERGE vii. It_events : internal table with a list of all possible events of ALV and their corresponding form names.
II. Tables :
i. t_outtab : internal table with the data to be output
B. REUSE_ALV_FIELDCATALOG_MERGE : This function module is used to populate a fieldcatalog which is essential to display the data in ALV. If the output data is from a single dictionary table and all the columns are selected, then we need not exclusively create the field catalog. Its enough to mention the table name as a parameter(I_structure name) in the REUSE_ALV_LIST_DISPLAY. But in other cases we need to create it.
The Important Parameters are :
I. Export :
i. I_program_name : report id
ii. I_internal_tabname : the internal output table iii. I_inclname : include or the report name where all the dynamic forms are handled.
II Changing
ct_fieldcat : an internal table with the type SLIS_T_FIELDCAT_ALV which is declared in the type pool SLIS.
C. REUSE_ALV_EVENTS_GET : Returns table of possible events for a list type
Parameters :
I. Import :
Et_Events : The event table is returned with all possible CALLBACK events for the specified list type (column 'NAME'). For events to be processed by Callback, their 'FORM' field must be filled. If the field is initialized, the event is ignored. The entry can be read from the event table, the field 'FORM' filled and the entry modified using constants from the type pool SALV.
II. Export :
I_List_type :
0 = simple list REUSE_ALV_LIST_DISPLAY
1 = hierarchcal-sequential list REUSE_ALV_HIERSEQ_LIST_DISPLAY
2 = simple block list REUSE_ALV_BLOCK_LIST_APPEND
3 = hierarchical-sequential block list
REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_COMMENTARY_WRITE : This is used in the Top-of-page event to print the headings and other comments for the list.
Parameters :
I. it_list_commentary : internal table with the headings of the type slis_t_listheader.
This internal table has three fields :
Typ : H header, S selection , A - action Key : only when typ is S.
Info : the text to be printed
E. REUSE_ALV_GRID_DISPLAY : A new function in 4.6 version, to display the results in grid rather than as a preview.
Parameters : same as reuse_alv_list_display
This is an example for simple list.
2. BLOCK REPORT
This is used to have multiple lists continuously.
The important functions used in this report are:
A. REUSE_ALV_BLOCK_LIST_INIT
B. REUSE_ALV_BLOCK_LIST_APPEND
C. REUSE_ALV_BLOCK_LIST_HS_APPEND
D. REUSE_ALV_BLOCK_LIST_DISPLAY
A. REUSE_ALV_BLOCK_LIST_INIT
Parameters:
I. I_CALLBACK_PROGRAM
II. I_CALLBACK_PF_STATUS_SET
III. I_CALLBACK_USER_COMMAND
This function module is used to set the default gui status etc.
B. REUSE_ALV_BLOCK_LIST_APPEND
Parameters :
Export :
I. is_layout : layout settings for block II. it_fieldcat : field catalog III. i_tabname : internal table name with output data IV. it_events : internal table with all possible events
Tables :
i. t_outtab : internal table with output data.
This function module adds the data to the block.
Repeat this function for all the different blocks to be displayed one after the other.
C. REUSE_ALV_BLOCK_LIST_HS_APPEND
This function module is used for hierarchical sequential blocks.
D. REUSE_ALV_BLOCK_LIST_DISPLAY
Parameters : All the parameters are optional.
This function module display the list with data appended by the above function.
Here the functions REUSE_ALV_FIELDCATALOG_MERGE, REUSE_ALV_EVENTS_GET, REUSE_ALV_COMMENTARY_WRITE can be used.
3. Hierarchical reports :
Hierarchical sequential list output.
The function module is
A. REUSE_ALV_HIERSEQ_LIST_DISPLAY
Parameters:
I. Export:
i. I_CALLBACK_PROGRAM
ii. I_CALLBACK_PF_STATUS_SET
iii. I_CALLBACK_USER_COMMAND
iv. IS_LAYOUT
v. IT_FIELDCAT
vi. IT_EVENTS
vii. i_tabname_header : Name of the internal table in the program containing the output data of the highest hierarchy level.
viii. i_tabname_item : Name of the internal table in the program containing the output data of the lowest hierarchy level.
ix. is_keyinfo : This structure contains the header and item table field names which link the two tables (shared key).
II. Tables
i. t_outtab_header : Header table with data to be output ii. t_outtab_item : Name of the internal table in the program containing the output data of the lowest hierarchy level.
slis_t_fieldcat_alv : This internal table contains the field attributes. This internal table can be populated automatically by using REUSE_ALV_FIELDCATALOG_MERGE.
Important Attributes :
A. col_pos : position of the column
B. fieldname : internal fieldname
C. tabname : internal table name
D. ref_fieldname : fieldname (dictionary) E. ref_tabname : table (dictionary) F. key(1) : column with key-color G. icon(1) : icon H. symbol(1) : symbol I. checkbox(1) : checkbox J. just(1) : (R)ight (L)eft (C)ent.
K. do_sum(1) : sum up

ADF: How to highlight cell(s) in chooseDate component

Hi,
I am using "ADF: ChooseDate" component for my application. Based on certain condition(s), I want to highlight a Date/Cell in the chooseDate calendar. I also want to customize the color for certain date (based on some conditions). I could not find a way to do it, Can someone please guide me.
Purpose of doing this: I want to design an application so that user can choose specific date (from calendar) for scheduling tasks. Once a task is created for a specific date then calendar should have some way of notifying user that some task(s) is/are already scheduled for specific dates. Thats why I am looking at a solution when dates can be highlighted (if there is any task scheduled for a particular date).
Best Regards,
Ajay

I'd speculate that the chooseDate component does not have the functionality you require. For this sort of funtionality I'd suggest you'd have to build your own component.
Not that is solves your problen, but if you're using JDev 11g, note that the ADF Faces RC chooseDate component does have attributes for disabledDaysOfWeek and disabledMonths.
