Button.Color - stays grey
« on: July 01, 2022, 06:38:21 pm »
I have a TButton and want to color it.
At runtime it stays grey. In Delphi this was a setting of "style" or so, which overwrote my user-color - but I cannot find it in Lazarus.
Neither I can find something, the Lazarus IDE hints like "ParentColor".

Please hint: What is is, which prevents my color to flush red?
Thanks.

Did you meant on Windows?

I do not use Windows but in my Object Inspector, it clearly shows TButton.Color is restricted on Windows. TButton and most of Lazarus default installed visual components depend on the OS, if the OS does not allowed it, you can't have it.

Otherwise there are several good looking visual components, for example:

@nicole: write on what kind of system you work. No post with information about your FPC/Lazarus Version, nor is it Win 10, Win 7 or a Linux distribution.

It looks you work on Windows, but no information.

Lazarus IS NOT Delphi !!!!

Lazarus is using normal the official widgetsets of the system and this is sometimes not compatibel to all features. But it works on all major widgetsets and platforms.

BTW: On Windows you have troubles to color a widgetset Button. On Linux no Problem with the color. So you can use non widgetset Buttons like Handoko say.

On windows you can't change the color. Period.
But you can use TBitButton.
This is not a limitation of Pascal, it is a limitation of windows.

The only thing is: maybe the color property should be hidden on windows, because it has no function.
And confuses people.

Black themes should be banned.

Install BGRAControls, and you can style buttons, checkbox, radiobutton, combobox, labels, panels, and so on.

A hidden property confuses the people more. Then they will claim - where is the property ... Delphi have this ... Bug ...

I think a better idea is, to write this in the documentation (maybe done) so you can say - RTFM

This 'Button Colour' problem is why I started using BGRAControls - extrordinary power!

Thank you for the answers and for the nice alternaties to TButton.

As you have guessed correctly: windows.
I am very new to Lazarus (coming from Delphi) and although I chose it, BECAUSE it is "write once compile everywhere", I am not aware of the many consequences of this, yet.

My next step will be to change to Linux. All is much work and starts - with a button.


PS: I just had a look at "Candy Controls": There seems to be all inside, I ever dreamed of!
(I like ATButton as well!)
