Font color in RadioGroupBox

[dgrhoads]

When I try to change the color of the font in a RadioGroupBox, the font color does not change.  Is this a feature or a bug?  All the radiobuttons plus the title should be affected.

I am able to underline text and change fonts in that box, but not the font color.

A known restriction of some widgetsets.

To see other restrictions you could look at the Restriction Browser ("View" > "Restriction Browser") where you can filter for the control and the widget set (indicated by the characteristic icons). (There is also a page "Restricted" in the Object Inspector, but I must confess that I never understood it.)

I just tested in Linux. Setting the color to clMaroon at design time worked both in the IDE and at run-time (which doesn' happen with e.g. TCheckGroup).

Then I added this line to the form's OnCreate handler (rgOptions is the radio group):

Code: [Select]

  rgOptions.Font.Color := clNavy;and it worked also, as can be seen in the attached image.

Couldn't test on Windows, so YMMV.

Uncheck the option For Windows:"Use manifest resource (and enable themes) in Project -> Project Options -> Application.

But it can "spoil" something else, like the image of the disabled buttons.

Drawing of controls has very large differences depending on the set of widgetsets. I created a similar thread

when I first encountered this behavior. Regular Linux users are less restricted in creative freedom than regular Windows users

Well feel lucky that you have that freedom..

Just remember that you should be designing any app with maximum restrictions in mind if you plan on cross porting it..

Not really; depends quite a lot on which combination of Desktop Environment+Window Manager+Composition Manager+Theme one is using. I have found that simply moving an application from, say, Ubuntu to Xubuntu discombobulates all your carefully thought out customizations

I added a new package, ExCtrls, to CCR (https://sourceforge.net/p/lazarus-ccr/svn/HEAD/tree/components/exctrls/) which contains extended versions of TCheckBox, TRadioButton, TRadioGroup and TCheckGroup that inherit from TCustomControl and thus are not drawn by the widgetset to give more freedom - see wiki and attached screenshot
