Title: LAMW UI questions
Post by: CC on September 25, 2017, 04:02:51 pm
Hi,
1. I need to change its color when a button is clicked to mimic grouped button behaviour (always only one is selected). Trying to change the color within the eventhandler crashes the app. Is there a way to do this properly?
2. Z Order has no effect. Is there a way to insure that a control appears on top of an other when overlapped.

1) How does the unproperly way look like? OS ? LAZ version ?

Note you may not be able to change the color on every widgetset for TButton: e.g. on windows that is not possible.

Trying to change the color within the on click event handler crashes the app. The process of handling a click involves some UI updates after the event handler code is executed. So I assumed that changing a property value it uses caused the crash. Maybe my code needs to be wrapped between some kind of "Begin update" and "End update" calls.

jmpessoa,
I have just realized, that for some reason my "Thank you" comment did not make into the topic earlier. So once again:
Thank you for creating LAMW and for your quick response.
Your solution works. There is small time-lag though, so I ended up putting every button into its own panel and coloring the parent instead. There is no delay this way. :)
