Howto catch "minimize panel"

[rkrijger]

I have LabWindows/CVI 7.1 and I want to execute some code when the user minimizes the main panel of my program.

I have written a panel callback and in the UIR i have asociated the panel callback with my main panel.

The source code of this panel callback is:

// PARENTcallback
int CVICALLBACK PARENTcallback (int panel, int event, void *callbackData,
  int eventData1, int eventData2)
{
 if(event==EVENT_CLOSE)
  QuitUserInterface(0);

 return 0;
}

I have a breakpoint on the if-statement. If I close the main panel (clicking the cross at the right top) I enter the panel callback at the breakpoint.

But if I minimize I do not enter the callback. Nor a "lost focus" (clicking on the windows desktop) is received...

What have I done wrong?!?

Best regards,

Robin

Hello Robin,

Check out Al S's comments in the following post.

Thanks.

Thanks for your reply. I noticed this thread, however it was of no help for me as I do NOT receive the "LOST FOCUS" event...

I have the "_" button and the "x" button on the main panel. When I pressing the "x" button, I enter my callback, when I press the "_" button I do not enter my callback...

I hope you can help me...

Well, it works fine for me......

[rkrijger]

Yep, this one works for me as well...

So any suggestions?!?

I can e-mail you my project as well?

Robin,

the most propable thing is, that the callback is not connected as a panelcallback to the appropriate panel. please check if the callback is connected to the correct panel. best use the uir-editor to generate all callbacks again after making sure that the panel has a callback defined. backup your old callbacks each time CVI asks you. then take a look if there are any new callbacks...... but i would advise you not to save this state of project. 🙂 this is only to take a look!

Thank you for your prompt reply. I will try this (in a copy of my project, not in the original) 🙂

Is it not more easy to check the corresponding *.h file of the *.uir file to see which callbacks are connected to which panels?!?

Robin,

"Is it not more easy to check the corresponding *.h file of the *.uir file to see which callbacks are connected to which panels?!?"
it depends on the number of panels and the amount of callbacks you included there (by using the editor). i for myself prefer the generation because i dont get messed up with different panelhandles..... but you can do it the other way as well....

Still not working in CVI7. But when I tried to compile the project with CVI8, I got the MINIMIZE event! Without changing anything to the C-source code... So...
