Tree Control Double Click Functionality

Hi All,
I'm trying to get a tree control to operate a case structure, and I cannot seem to get the Double Click invoke node to output my tags from the tree. Anyone know what I may be doing wrong?!
Thanks,
Derek

Tree control double click default behavior

Hi all,
Tree control have default behavior that expand/ collapse item when double click event occurs on parent item.
How do I to avoid this behavior to use custom double click event without open close nodes?
Thanks,

Hi,
I was not able to disable the default event however I realized a VI that could be useful for you.
I've used a method to force all the tree items to be collapsed.
Take a look at the attached image.

In Yosemite, Magic Mouse double-click function doesn't work

On my iMac running Yosemite 10.10.2, the double-click function on the Magic Mouse no longer works. So to open a folder, or anything for that matter, I must always do click-control ---and that doesn't work for everything. For example, I can't double click on a character in Glyphs, so this renders Glyphs useless. And so on... I have gone into preferences to see if anything was amiss in the settings, but everything checked out fine. Is there a fix for this, or do I have to wait for the next upgrade for Yosemite? Help! Thanks... --Royce

What's the answer to this mouse problem, please? Why does my double-click no longer work on my magic mouse since downloading Yosemite 10.10.2 to my iMac?
What's up Apple?

Drag and hover double click function isn't working

Hi people, I have been unable to click hold and drag items into folders and use the double click function when it hovers over.
It just seems to have turned itself off. I have looked at settings and everything is as it usually is. Can't seem to get it working. Didn't occur with any particular software update just stopped working.
Can anyone help get this working again?
Cheers

It might be a mouse issue.
I suggest rebooting, and if that does not help, reset the PRAM

ADF: double click functionality

I am developing a Fusion Web Application in JDev 11gR1.
I am trying to call a method in a managed bean if the user double clicks on a node in a tree or a row in a table. The only way I have found to do this is as follows:
- add the following to the outputText of the tree or table:
<af:clientListener type="dblClick" method="handleTreeDblClick" />
<af:serverListener type="doubleClickOnNode" method="#{pageFlowScope.actionBean.treeDoubleClick}" />- add the following to the .jspx page:
<trh:script>
handleTreeDblClick = function(event) {
var source = event.getSource();
AdfCustomEvent.queue( source, "doubleClickOnNode", {}, false);
</trh:script>This seems very convoluted. Isn't there a simpler way to do this?

I had a similar problem - I wanted to expand a tree when clicking on its label (not only the + sign). I found some articles that also suggested using af:clientListener. It is not so unusual because dbClick is DOM event handled by javascript. If you want to skip javascript - use command buttons and links :)

Double click functionality in Webdynpro ABAP ALV

Hello!
I have web dynpro application with ALV Table.
I need to reproduce the standard R/3 functionality: after the double clicking on the table row the new window with content of that row's fields should appear in the form layout .
For example, such functionality we have in the RSDMD transaction.
So I have two questions:
1. How to catch double click in the alv table of the Web dynpro application;
2. How to represent information from the alv table row in the form layout?
Could you please help me?
Thanks,
Mariya

Hi Maria,
Say suppose I am displaying the information from SFLIGHT in an ALV format & when I click on any 1 row's CARRID I would like to fetch the corresponding BOOKING details for that particular combination of CARRID, CONNID & FLDATE then I can proceed as follows:
1) Make the CARRID cell of your ALV to appear as an LinkToAction
2) Create an event handler for the ON_CLICK event of the ALV & within this event handler fetch the information about the row's CARRID, CONNID & FLDATE. Call a popup window and display the corresponding information in this row.
Below is the code to make your CARRID field as an LinkToAction:
METHOD wddomodifyview .
wd_this->build_alv( ).
ENDMETHOD.
METHOD build_alv .

SQ01 double click functionality

Hi everybody!
I have implemented an ABAP query using transactions SQ01/SQ02. Now I would like to enhance its functionality by providing a 'drilldown'capabilty.
I. e. if the user double clicks on the field MATNR of my query, transaction MM03 should be started showing the details of the corresponding material.
Is this possible? If it is, how do I do that?
Regards,
Joerg

Hi
While you're in the query (trx SQ01) go to: GO TO->Report Assignement

Magic Mouse: Double-click function

I have "secondary-click"(right) activated on the "magic mouse" and it's great if I want to open a drop-down list on a page.
However, on the "mighty-mouse" which I had before, the "right-click" was set up to act as a "double-click" which was very handy for opening documents and folders etc.
Is there any way to set up the "magic-mouse" so that a "right-click" will act as a "double-click"?

You could try a third-party driver like BetterTouchTool (http://blog.boastr.net/?page_id=1722)

Double Click Functionality - Help Please

Hi,
In ControlPanel >> Mouse Properties >> there is an option for increasing the double click speed.
Similarly , i need to have a JSlider , getting User Input from the JSilder Object, thereby increasing the double click speed for my Swing Application.
how to do this one in swing ???
Help please....
Thanks,
Mani

Windows tells java how fast the clicks were. To change this property in java gets very confusing, because you will need to time the interval between clicks since I don't think you can change this system setting from your program. It is far easier to just stay with the double click speed set by windows.

Double Click functionality

Hi,
   I have a report where material is one of the output field.
When user double clicks on material number it should call MM03 from the report and it should directly take to Accounting 2 view.
How can it be done.
Do let me know.
Regards,
SP

Hi Sandeep,
when you double click on the list.it triggers AT line-selection.   event.
so when you double click you write your code in this event in the following manner to stop at MM03 at accounting 2 view
AT LINE-SELECTION.
case sy-lsind.
when 1.
    ( First do the recording of MM03 and get the BDC data table populated with program name and screen number and fields required and also the OKCODE to be executed )
    ( Then call the tansaction using
     CALL Transaction MM03 using <bdc_table_name> mode 'E'.
mode E because you want the transaction to be stopped at accounting 2 view. )
encase.
Regards,
Ravi

How to control double click seepd?

hi,
I downloaded JDK 1.6 for my software, but it seems that the mouse double click does not work properly. You have to double click it really fast or more tan twice for the double click to work. How can I increase the interval between the two mouse clicks?
The platform is both Windows and Linux/Solaris, but the windows is more urgent.
Thanks in advance,
Sean

Try this method.
jButton1.setMultiClickThreshhold(long milliseconds);This will work only in action event, will not work in mouse event.

Turn off double click function in iOS 7

I would like to know how to turn off the "double click" feature in iOS 7 that brings up all apps/websites you've been to. I pre-ordered a Christmas gift for my son & when he double clicked the button he scrolled right by it! Good thing I noticed before him...but I am not a fan of this feature :)

Great to hear that you find the iPad useful for online shopping
There is no way to turn off the screenshot of the app's last state that appears above the app icon after double tapping the home button. If you are done with an app, you might consider closing it by swiping up on the screenshot that appears after double tapping the home button.
You can leave Apple feedback at http://apple.com/feedback/ipad.html

I can't use the double-click function of my trackpad anymore...

Double click in ALV tree output????

Hi all,
I am able to display output in tree format. But I want to add the double click functionality to some of the fields in output. Means if I double click on some value in output tree, it should call some transaction. Please help me with this issue of double clicking.
Please tell how to handle events in this report tree display.
For the following code its displaying output in tree format and in right way. But i need to add double click functionality to this.
So provide me some sample program for this one....
* create hierarchy
CALL METHOD tree1->set_table_for_first_display
          EXPORTING
               it_list_commentary   = lt_list_commentary
               i_background_id      = 'ALV_BACKGROUND'
               i_save               = 'A'
               is_variant            = ls_variant
          CHANGING
               it_sort              = gt_sort[]
               it_outtab            = itab_outtab
               it_fieldcatalog      = t_fieldcat. "gt_fieldcatalog.
* expand first level
CALL METHOD tree1->expand_tree
         EXPORTING
             i_level = 1.
* optimize column-width
CALL METHOD tree1->column_optimize
           EXPORTING
               i_start_column = tree1->c_hierarchy_column_name
               i_end_column   = tree1->c_hierarchy_column_name.
In grid ALV we can have double cilck functionality using code:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
       EXPORTING
            i_callback_program       = w_repid
            i_callback_pf_status_set = 'PF_STATUS'
            i_callback_user_command = 'USER_COMMAND'
            is_layout                = ls_layout
            it_fieldcat              = gt_fc[]
Here we can write subroutine for USER_COMMAND and handle the double click evenet. But tell me how to provide this in tree ALV.
