Lazarus Release 2.2.4

[dssmex]

This has nothing to do with ARM processors. Show us some code - compilable code -... Then you will get more reasonable answers.

Just only, New Project- add an showmessage inside of OnShow Event and run the program in a raspberry pi 4. Sometimes the code inside onshow dont do nothing.

Remove the close, because ShowMessage is not modal. That goes for every platform btw.

This happen with or without close.

... because ShowMessage is not modal. That goes for every platform btw.

I probalbly misunderstand you here, but ShowMessage shows a modal dialog on all platforms AFAIK.

On Linux it is not modal, as you can see from the emalgamation of popups while using -glh.
That should not happen if ShowMessage was modal.

[PascalDragon]

ShowMessage is supposed to be modal, because it's only supposed to return once the dialog window is closed. This means that (per thread) there can only be one such window open.

[Thaddy]

Which isn't the case on Linux/gtk2..
I know all that.

A modal Window should halt execution before any other code gets executed in the same thread.

[Bart]

Which isn't the case on Linux/gtk2..

Which makes both of us wrong.
You: stating that ShowMessage is, on every platform, not modal.
Me: stating it is modal.
But you seem to be worng on more platforms than I. So, I win

Hello.
Where can I place a proposal for the FPDoc documentation module?
Suggestion: after renaming the variable (by F2), as well rename the variables in the xml file.
