Hide Window app icon

Targets Windows
1

Is there a way to hide the small app icon in the Window (top right)?

Also, is it possible to change the window topbar color?

Basically I need to have something like the System Settings window

I know I can use a Plain window but in that case I need to emulate the top right buttons (close, size, …) and it would look odd on Vista (with Window 8/10 buttons).

EDIT changing the color is already answered here : https://forum.xojo.com/30904-windows-10-window-titlebar-color

I created an icon for my app which was completely transparent, made the title empty and set the menu to none. The result looks like this

Possible issues:

  • The app will have an empty 128x128 icon, so it can popup in the Explorer as being empty.

Or am I missing something?

I looked around for some code that could serve as base for a declare, found nothing.

While I am reading this thread in Firefox, I see that Firefox’s window has no app icon at the Top-Left (not Top-Right, is that what you meant, Christoph?)

Yes I meant top left … sorry about the confusion.
Waynes trick does work but it also means there is no icon for your app in the Explorer when it displays 128x128 icons.

I guess the only way to do this is to fake it with a Plane Box window.
Creating the close/minimise/maximise buttons isn’t difficult using canvas but is there a way to grab the images from the OS so when you you run it on Vista, it return the Vista close/minimise/maximise images?
Of course I can include both Vista and Windows 8/10 images but I think it can be done with declares too.

I do not even know where are the menus (where is ctrl+0) ?

Right click tabs bar and choose menu bar.

I think this will do some of what you want… drop it in the open event of the window.

[code] #if targetwin32
const WTA_NONCLIENT = 1

const WTNCA_NODRAWCAPTION = &H00000001
//Prevents the window caption from being drawn.
const WTNCA_NODRAWICON    = &H00000002
//Prevents the system icon from being drawn.
const WTNCA_NOSYSMENU     = &H00000004

declare function SetWindowThemeAttribute lib "UxTheme" (win as ptr, attributetype as uint32, atts as ptr, size as uint32 ) as uint32
dim atts as new MemoryBlock(8)
atts.UInt32Value(0)=WTNCA_NODRAWCAPTION or WTNCA_NODRAWICON or WTNCA_NOSYSMENU
atts.UInt32Value(4)=WTNCA_NODRAWCAPTION or WTNCA_NODRAWICON or WTNCA_NOSYSMENU

dim res as uint32= SetWindowThemeAttribute(ptr(self.Handle),WTA_NONCLIENT,atts,atts.Size)
