Thank you for reporting this. Good news is that this was fixed about 3 years ago in the "maint" branch. Can you please 'git clone' (or download) that, and try again.

Hello. If you like custom layout, maybe you could take a look at: https://github.com/fredvs/uidesigner_ext/releases/tag/1.9.1

It has plenty of build-in layout.

[fredvs]

And to set a style for your app, after you choose one in the menu "Review", for example "Chrome Silver flat menu".

Copy the unit from uidesigner_ext source (source are here): https://github.com/fredvs/uidesigner_ext/

/uidesigner_ext/src/fpg_style_round_silver_flat_horz.pas

into the main directory of your program (you may add all those you want to switch live for a other style for your app).

Then in the main unit of your program, add this (and other styles needed):

uses
...
fpg_stylemanager,  // this to enable styles
fpg_style_chrome_silver_flatmenu, // add more styles if you want
...

And in the MainProc, add this after fpgApplication.Initialize;

  if fpgStyleManager.SetStyle('Chrome silver flat menu') then
       fpgStyle := fpgStyleManager.Style;

You may also in your app change with other style using fpgStyleManager.SetStyle() depending of what style-units you added in the uses section.

The name of the style is defined at each end of fpg_style_xxx.pas in initialization section, for example fpg_style_round_silver_flat_horz.pas:

initialization
  fpgStyleManager.RegisterClass('Chrome silver flat menu', TExtStyle);

I just search how to change lazarus project's target application's skin, So I find fpGUI.

Note that fpGUI is completely independent of Lazarus. You can use Lazarus to edit-compile the source but fpGUI needs its own form designer: uidesigner: https://github.com/graemeg/fpGUI/tree/develop/uidesigner

(or possibly uidesigner_ext as presented previously)

Glad you like it @bird00101011 . :-) fpGUI includes built-in themes. They are managed by the fpgStyleManager, defined in the fpg_stylemanager.pas unit. The fpg_style_win2k.pas is currently the default for fpGUI. Simply comment out the cDefaultStyle line in fpg_style_win2k.pas, and put a similar line into any of the other styles you would like your fpGUI to default too.

You can also switch styles at runtime, when you start up your application, by simply passing in the --style <style-name> command line parameter.
