JComboBox look problem

Here is what I need to do.
I have to build a ComboBox that will have a different graphic than the arrow pointing down.
I want to place a .gif instead of the arrow. Also, the comboBox should always show the entire .gif files, not just a part of it. Basicaly, I want the height of my combobox to be the same as my f.gif file.
Right now, I can place a .gif file, but if my ComboBox is small I will not see the .gif completly.
Thanks

How about:
combo_box.setSize( img_icon.getIconWidth(), img_icon.getIconHeight() );

JTable JComboBox display Problems

I have a JTable which uses JCombobox's to display one column's infomation.
Most times this works perfectly well and displayes correctly.
But sometimes the combo box will not be displayed at all in the table (just get a white cell). When clicked apon the combo box works correctly and the information is in the cell, as it is used latter on in the program . Once a value is selected in the combo box the cell goes back to being white.
The only corrilation I can find is that this seems to occure more frequently when I am debugging or running alot of programss in the back ground.
Any suggestiongs on where I can start looking.
Thanks

Sounds like the Cell Renderer is not working as expected.
- that might be a starting point for you, hard to say much more without
any code...

JCombobox selection problem

Hello,
I have some problem implementing events associated with JComboBox. My requirement is "the event should get fired only when an item is selected in the combobox". It may occur thet using arrow keys I can traverse all elements in the combobox and on item change the event should not get fired. I tried with itemstatechanged, actionperformed but no result.
Any help will be appreciated.

Ranjan

JComboBox listener problem

Hi all,
I have following problem, i use combobox and i need to write listener for selecting item.
But both ActionListener and ItemListener are unusable for me, because i dont know how to differ between selecting item when combobox is poped up.

Don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the posted code retains its original formatting.
Don't know why the code works the way it does, but the code is wrong. The correct way to add a row is like this:
//model.addRow(data);
String[] rowData = { " ", " ", " ", " "};
model.addRow(rowData);

JComboBox addActionListener problem?

HI,
i am using JComboBox to add each item action perform of use StyleEditorKit.FontSizeAction("String", int), but i only can add one item action perform only. See my code any problem...
for(int i>12;i<=50 ; i++){
              comboBox.addItem(" "+i);
           // i want to loop each item can function
            comboBox.addActionListener(new StyleEditorKit.FontSizeAcion("i ", i)Thanks

FontSizeAction is able to set the size to a value delivered in String format as the command String of its ActionEvent. Unfortunately, the JComboBox doesn't deliver the String value of the selected item as command string but an arbitrary value to be set once. So you have to wrap your FontSizeAction in a custom ActionListener of your own where you retrieve the selected item, cast it to a String and pass this value to FontSizeAction as the command String of a new ActionEvent object.
You should also get rid of that whitespace when creating the size value, String.valueOf(int) is a better way to create a String for an int.

JComboBox Dropping Problem

Hi, I have a JComboBox in a table cell with all the Item I need. But the problem is when I click on JComboBox, dropdown menu pops up and immediately hides automatically. And cannot allow me to choose anything.
Any suggestions plz.
Thanks

You've got a coding problem, so read this section from the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html]How to Use Combo Boxes for example on how to do this correctly.

JComboBox MouseListener Problem

Hi!
I have problem in getting mouseEntered event from a JComboBox. I have registered a MouseListener with it but it doesn't fire any mouseEvent. Anyone has any idea how to get the mouseEntered Event fired from a JComboBox??
Thanks!!

Even I, have a similar problem. My obejective is to display the tooltip, When I move the mouse over every individual item in the combo box. The combo basically has a JList. So, I overrided the getListCellRenderer(...) method. It is not displaying the toolTip when the combo initially has no selectedItem. If there is a selected item, the first time itslef, it displays the toolTip. If theres no selectedItem, it displays the toolTip when I move the mouse out of the combo(when the combo is expanded). Tried all possible combinations... but doesnt work. Have set the toolTip with setToolTipText() method... and when I print the toolTip with getToolTipText() method. It prints correctly, but isnt getting displayed.. :-(

JComboBox Editing problem

hi all ,
I have problem with JComboBox
like this :
JComboBox comTech = new JComboBox();
comTech.addItem(" ");
comTech.addItem("one");
comTech.addItem("two");
the problem is I want first( comTech.addItem(" ");) item is Editable remaing are uneditable
I am not getting any solution if anyone knows please send the solution
thanks

You missunderstand the use of JComboBox. A JComboBox is used to allow the user to selection from a list of items.
An uneditable combox allows the user to select an item from the list.
An editable combo box allows the user to select an item from the list or to enter there own value. It does not allow you to change the value of the entries in the list.
See this section from the Swing tutorial on "How to Use Combo Boxes":

2 JComboBox sync problem

Hi, im getting crazy with this error. I have two different JComboBox with two differents DefaultComboBoxModel.
The first shows a list of files.
The second shows a data list from the selected file in the first.
When i select a different file in the first combo, i want to change the data list in the second combo. So i call the removeAllElements method in the DefaultComboBoxModel, but i dont know why, then the second combo code is executed too (it shouldnt) and i get an error.
The code is something like this:
cmb1 is a jcombobox linked to dcbm1, which is a defaultcomboboxmodel
cmb2 is a jcombobox linked to dcbm2, which is a defaultcomboboxmodel
MyObject is a customized class which has two fields: a Vector and a String. There is a Vector of MyObject, where is load the file data.
void cmb1_actionPerformed(ActionEvent e){
    dcbm2.removeAllElements();
    // Load the file
    // Get data load on vector (class Vector)
    // Then, send data from vector to 2nd combomodel:
    for (int i=0; i<vector.size(); i++){
      mo = (MyObject)vector.get(i);
      dcbm2.addElement(mo.getString());
void cmb2_actionPerformed(ActionEvent e){
    dlm.clear();                                                    // ListModel which i use to show data
    int x = cmb2.getSelectedIndex();
    m = (MyObject)vector.get(x);                       // This line throws the error (ArrayOutOfBounds). x=-1
    vector2 = m.getVector();
    for (int i=0; i<vector2.size(); i++){
      dlm.addElement((vector2.getString()
}So thats my problem. When i select an item in the 1st combo, the 2nd combo code is executed too, throwing an ArrayIndexOutOfBounds because there is no item selected

as I see, in this listing, you did not try using what I told you before, try using this:
public void actionPerformed(ActionEvent e) {
     Object obj = e.getSource();
     if (obj == cmbFiles) {
          parser = new MyXMLParser((String) dcbmFiles.getSelectedItem());
          try {
               carrera = parser.read();
          } catch (Exception z) {
               z.printStackTrace();
          cursos = carrera.getCursos();
          for (int i = 0; i < cursos.size(); i++) {
               cur = (Curso) cursos.get(i);
               dcbmCursos.addElement(cur.getCurso());
     } else if (obj == cmbCursos) {
          dlmAsignaturas.clear();
          int x = cmbCursos.getSelectedIndex();
          cur = (Curso) cursos.get(x);
          asignaturas = cur.getAsignaturas();
          for (int i = 0; i < asignaturas.size(); i++) {
               dlmAsignaturas.addElement(
                    ((Asignatura) asignaturas.get(i)).getId()
                         + ((Asignatura) asignaturas.get(i)).getGrupo().toLowerCase());
}

Quick Look Problem ?

I was just wondering why when I use QuickLook with 2 monitors, anything I QuickLook, picture/Music/Video etc.. always goes over to my other Screen I have hooked up to my iMac ? I want to quick Look it on the main screen (iMac Screen) not have to turn on the Other monitor every time I want to quick Look something. I think it's rather annoying having to turn that other monitor on all the time to view what I want, or drag it over to my main iMac screen to see. Now if I unplug the Other monitor it's just fine. Only when I have another monitor plugged in it does this.
I looked up and down in the System Prefs to figure this out, and found Nothing. It's either a bad part on apples side, or there is something I"m missing.

I had that same problem and I believe that I just "Quick Looked" a jpeg which opened on my other monitor (the wrong one) and while it was open moved the window to my main monitor. Once I did that I closed the quick look window and then reopened the same file using quick look again and I found it then opened on my main monitor.
If this works then be carful about closing a quick look window. Make sure to close it on the monitor you want quick look to open on.

KDE 5 auth/look problems

I upgraded to KDE 5 (Plasma 2, KDE Frameworks 5.6, KDE Apps 14.12) and I must say it was a huge error. I completely reget doing it, and I should have learned from the mistake with KDE 4.x.
Anyways, It's already done. Now I'm having quite some problems.
The first one, which is the most important is that KDE auth (or polkit, or I don't know what name it has because apparently KDe guys like changing names every 2 months) isn't working.
I open systemsettings and try to enable the auto-login feature, and then a password dialog shows up, asking for my password. I really don't know if it's asking for my user's password or root's password,
but this really should make any difference as both passwords are the same (please, right now I don't want to hear anything about how bad that is and how unprotected I am. Focus on my problems).
Anyways, after typing my password, the dialog just says that's not the password and doesn't apply the changes. Why is this happening?
The second problem is that all KDE4 apps (Dolphin, for example) look really bad. The Wiki says to check my styles, but hell I did check and recheck them and I can't see how to fix that. How am I supposed to workaround this bug?
Regards

No issues with autologin or authentication on a fresh Plasma 5.2 system here. KDE accepts my normal user password. You could have a look at /usr/share/polkit-1/actions/org.kde.kcontrol.kcmsddm.policy if there is something wrong with the defaults settings
For the second issue, check my own post from here: https://bbs.archlinux.org/viewtopic.php … 1#p1495601

JTable with JComboBox/JSpinner problem

The following code has a JTable with 2 columns.The lst column has JComboBoxes, the 2nd column has JSpinners.I want to set the spinner range of values based on the selection of JComboBox. The JComboBox selections are "small" and "large". For "small" the spinner should range from 0..49, for "large" from 50..99. When a selection is made, MyTable.itemStateChanged() is called, which in turn calls SpinnerEditor.setValueRange(). This sets an array with the desired values and then sets the model with this array. However, it sets the range not only for the row in which the combo box was clicked, but all rows.
So in MyTable.setCellComponents(), there is this:
spinnerEditor = new SpinnerEditor(this, defaultTableModel);
modelColumn.setCellEditor(spinnerEditor);
If the table has n rows, are n SpinnerEditors created, or just 1?
If 1, do n need to be created and if so, how?

However, it sets the range not only for the row in which the combo box was clicked, but all rows. Yes, because a single editor is used by the column.
One solution is to create two editors, then you override the getCellEditor(...) method to return the appropriated editor. Something like:
If (column == ?)
    if (smallOrLarge)
      return the small or large spinner editor
    else
       return the large spinner editor
else
    return super.getCellEditor(...);

JComboBox color problem

Problem:
Setting the button background color via UIManager.put(....) actually changes part of the background of my comboboxes. I also set the combobox background with UIManager, but it only applys this color where the data is within the combobox. The area where the down arrow is (on the combobox) is the color that I set the buttons to.
Question:
Is there a way to prevent this line:
UIManager.put("Button.background", ButtonColor);
from affecting my combobox background?
I want to achieve custom user colors for the various components within the application, but I want to set these colors in one location, through UIManager.put(...).

Try storing a custom Object in the model, not a text string. The object would contain the text, foreground and background color. Then the renderer simply gets the value to be rendered, casts it to your Object type and retrieves the 3 pieces of information which it uses to set the text, background and foreground. No need for if / else statements. Here is a simple example:
