TitleBarIcons

GPI · Post by **GPI** » Sun Feb 29, 2004 9:41 pm

I saw in El_Choni TailBite-Program a additional icon. With icon it is possible to "stick" the window on top.

My rountines based on El_Choni's routines, but i change a lot.

The code shows, how to add a additional costom icon.

At last somebody notices the d*mn button in the titlebar XD (it took me some time to get it working properly). However, I haven't been able to attach a tooltip to it yet.

@GPI, nice work. Maybe you're able to attach a tooltip to it?

BTW, my code, like yours, uses a bitmap to draw the icon, but maybe this looks awful in XP, I don't know. Would there be a way to draw the icon with the colours used by the user?

EDIT: now I see that's what your code does, I'll use that trick if you don't mind

Not easy, because the button is a fake...
And i don't see any possibility to get a message, when the mouse-cursor moves out of the icon...

No problem: But maybe you should store the created bitmaps (you should check, if the icon-size has changed and recreate the icons if necassary.)

But that's what my code does... What it doesn't check is icon colours and shape, like yours.

I think, we are talking about two different things...

Look in the prepare-Icons-Segment of my code.
I create a window with some Toggle-Button-Gadget and set diffrent "styles" (normal, pushed, disabled, disabled-pushed). With this icons i create my Icon for the Titlebar. And thats my trick to create XP-Styled Icons on a XP-Sytem with style on. Also when the user change the colors of the buttons, my routines can handle this.

Btw: I think, that a tooltip is impossible. I can set, that a tooltip popup on a rect (and not on a gadget), but this rect must be in the client area. The titlebar is not the client area...
When i can get a id to the no client area.

Found something funny: It is possible to give the tooltip-rect negativ values (i think, this is a bug and should not work; but it work under win98se and winXP prof).

Code: Select all

No external images needed now. Still no tooltips in this one, I'll try to add them looking at your code:

EDIT: now it does exactly what I needed, thanks to you

I've added it to TailBite.

Our codes are different: your code is useful to add title buttons in any app, mine is only an example of using one titlebar button. Yours could maybe make it into an userlib.

BTW, I know you must have some reason for this, but I don't know which: why do you create a memory context in every WM_NCPAINT? Can't you reuse always the same, as in my code below or in the original code?

Code: Select all

When you use SelectObject_() on a bitmap, this bitmap is locked and can't be used with any other hDC. But my routines should work with many diffrent windows and with the same images at the same time.
