hi,
how can i close several panels with different names with one click ?

Hi,

do it with a function like this, actvated by a mouse click:

function resetAllDrawPan () {
reset (dAnnoTxt, SHOW);
reset (dLinesPan, SHOW);
reset (dAreasPan1, SHOW);
reset (dAreasPan2, SHOW);

}

thanks for your info, but there must be a faster way instead to write all panel names and reset them one by one, or ?

It's the easiest way.
You could write a whole custom panel handler, that stores any panel in an a linkedlist or array, and walk through that to reset them that way... but that's more work.

I did not tested but maybe you can make array of panels and close all on a for loop.

I hope it helps

Actually, panels are already in a linked list. You can find the first panel with ptr_first (void* object); and find the next with yourpanel.link.next.

You can hide all panels like this:

I think this is the easiest way.
