Mint Cinnamon: Cannot show minimized form
lazarus / 32-Linux

The following code shows a minimized form on Windows.
In Linux Mint Cinnamon it does on the second time - the event which
executes the code needs to be fired manually twice before the form is
shown, after the first execution nothing happens

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
self.WindowState := wsNormal;  self.Show;
Also, the following code works from the first time:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
self.WindowState := wsNormal;  self.Show;  ShowMessage (''); 
self.Show;
The following code improves nothing:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
self.WindowState := wsNormal;  self.Show;  spleep(500);    self.Show;
Any idea how to fix this? I have not tried those (non)syncronous
things, if no better solution exists, I will try them.

Hello.

Mint-Cinnamon uses Muffin window manager (a fork of Mutter WM).
And it has features "by design" that are indeed not fully compatible
like other working WM.
(And Muffin devs do not have plan to fix it).

But the ShowMessage sort of solves the issue, so probably I can
emulate a ShowMessage, which shows nothing?
I will try with a timer.

EDIT:
I made it work the following way:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TfrmMainForm.ShowApp;begin  self.WindowState := wsNormal;  self.Show; 
self.BringToFront;  self.SetFocus;  {$IFDEF LINUX}  tmrTray.Enabled :=
True;  {$endif}end; procedure TfrmMainForm.tmrTrayTimer(Sender:
TObject);begin  //Used only in Linux, to override a bug in Mint
Cinnamon  self.Show;  tmrTray.Enabled := False;end;
