Handling double clicks on text field

[former_member202335]

Hello,

I have a screen with a text field containing a material document number. I have enabled double-clicks on this text field by setting the 'Resp. to DblClk' check box. However, I still don't know how to handle events for double clicks. I mean when I double-click the text field, how do I identify the event-type and the source of the event. As far as I know, there is no way to set a function code value for a text field.

Please reply ASAP.

Thanks and regards,

Provided you have the PF-Status containing a function code for the F2 / double-click selection you should be able to pick up this action in your PAI user command logic - if you use the "get cursor field" command you can tell where the cursor was when the user selected the action and react accordingly.

Hi Jonathan,

Thanks for your response! I am already using the F2 function key for some other purpose. Is is possible to assign the funtion code to a different function key? Also, how to I associate the function with the double click event?

F2 is traditionally "pick" or "select" or "drilldown" and the SAPGui will issue an F2 if you double-click on a field... but even if you are already using it for other purposes by using the "get cursor field" you can distinguish where the user was drilling into and react accordingly i.e. use existing logic unless the field they are on is the one exception you want to have special processing for.

this code might help u..

When you double click on a text line in the TextEdit control, you want it to be prefixed with a '*'.

The line number of the TextEdit control that is double clicked, is retreived using method GET_SELECTION_POS. The internal text table is reloaded froim the TextEdit control with method GET_TEXT_AS_R3TABLE. The position of the double click in the TextEdit control is used to find the entry in the table, and the entry is prefixed with '*' and loaded into the TextEdit control again.

The program should be changed so that the internal table i_texttable is global, and a global flag g_loaded added. The load of the table should be moved to the PBO module. The changes in thje code are marked with red. The whole program now looks like this:
