Hi all.
I am trying to emulate a togglebutton/checkbox in a custom toolbar.
Right now I have settled for having two toolbar buttons with different
icons. Only one of them is visible and when it's pressed it toggles the
visibility of both buttons using the code below (which sets visibility
of a single button with a given label).
It works OK but only as long as the user doesn't fiddle with button
visibility :-). Is there a way of changing a toolbar button's icon
directly from Basic code ? I could not figure out how to do it.
Hi Jan,
Your solution looks it a little bit strange. You can set the image of a
toolbar button with the help of an image manager. Look at the following
Basic code which uses the image manager to set an image for a button
that references a Basic macro. I am sure you can adapt the code to your
needs.
Regards,
Carsten
