Dark mode

Mister Nages, in time: when changing the window color, this has a side effect in other applications. For example: the google chrome page is completely black. Its power is incredible, Mister Nages. See if you can avoid this by closing the program window, perhaps keeping the original colors and restoring on exit. Just an idea.

Which version of Windows are you using?

You need not include individual COLOR_* defines in your program. Just include "wcolors.ch", which contains all these defines.

Now I need to Change the WINDOW TITLE COLOR. Where it is written:


Assign your colors to COLOR_ACTIVECAPTION, COLOR_INACTIVECAPTION, COLOR_CAPTIONTEXT, COLOR_INACTIVECAPTIONTEXT.

Please note that these changes will work only with Windows XP to 8.1.
This does not work with Windows 10 and later.

So, if you write your applications to be used only on older OS like Windows XP to Windows 8.1, then you can use "SetSysColors" to set your own theme, Dark or something else. Your applications will not get the desired effect on Windows 10 and later.

The point I am trying to make is that if you read any articles or advices to use SetSysColors() to implement DarkTheme, they are all old and obsolete. If we proceed in this direction, we are only wasting our time.

hi,

Color for Titlebar under Windows 10 /11 now called "Accent-Color"
you reach it under "personize" -> "Color"
you also need to enable Color for "Titlebar & Frame"

in Registry you will find it under
Code: Select all  Expand view
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\DWM
AccentColor


---

you can GetSysColor() and save Value before use SetSysColor()
i do load Information like Color from DBF or INI File at Start
greeting,
Jimmy

how can we do this?

For Windows 10 we need to know how to set these colors
COLOR_ACTIVECAPTION, COLOR_INACTIVECAPTION, COLOR_CAPTIONTEXT, COLOR_INACTIVECAPTIONTEXT, COLOR_SCROLLBAR

Yes.
I too would not use this approach in my applications.
