Set Title On Center

[MrCreatoR]

Hi to all,

Is it possible to set titles at the center of created GUI?

Or better, if it will be some function that use hWnd to set titles in center of window, it will be great.

I have no idea how even to start such a function... maby a DllCall's?

Thanks.

Are you talking about centering the window caption text or just writing centered text in the window itself?

[Hello Me You]

I do not know what he wants but I want to center the text of the window title on the title bar. Is it possible?

Simple to understand... and as a simple solution

GUICreate("                                  My GUI")
GUISetState()

Sleep(5000)
Exit

I know thats not exactly what you wanted but....

#1

it does the job

#2

All the others can see exactly what you wanted to do

[Hello Me You]

Any better solution?

Thanks, but i tried this, and as eHrgo say, on vista (or windows with some addition styles) it will be useless.

OK! thanks you very much! it' s work... but... how can i make the background of title to be transparent? (just like the original title)?

Edit: Correct some serious spelling mistakes

This example uses the colors that are set on your machine as the active caption and inactive caption for the background and white for the text color. You can play around with the colors that are passed in the SetBkColor and SetTextColor calls if you want to use different colors for the background/text.

If you're using a theme for your desktop (like Vista Aero), you'll have to change the color calls to be theme aware. More code than I care to write at the momemt.

No, i don't using any thems, and on my desktop the icons have transparent color...

The active caption and inactive caption this is the color of selected items? if not, then i have another question (sorry for litle offtop) - How can i get the system color of selected items? i mean, that color that around the selectd file (by default its dark-blue). The function _API_GetSysColor($iColor) can get it?

P.S

Thank you for you help, and see here

No, the active/inactive caption colors are the background of the window caption when the window is active/inactive. When an item is selected, I believe that the constant is COLOR_HIGHLIGHT and the text itself is COLOR_HIGHLIGHTTEXT. Here is the MSDN link for GetSysColor that has all of the color constants.
