Add an icon to a program

[Armoured]

Hi
How I can add an icon to a Linux PureBasic program?
In Linux the icons are external files?


Thanks

[walker]

yes, the are external files...
add an icon with:

Code: Select all

gtk_window_set_icon_name_(*window, stockitem$);

if it's a stock item
(*window a pointer to your Window
stockitem$ is a Gtk-stockItem)
or

Code: Select all

gtk_window_set_icon_(*window,*icon);

*window a pointer to your Window
*icon must be a pointer to a GdkPixbuf
or

Code: Select all

gtk_window_set_icon_from_file_(*window, *filename, *err)

*window a pointer to your Window
*filename ..... well the path to your icon
*err a variable for which contais the error (if any occurs)

I guess the function you'll need is the third one.... (don't know it exactely but I think you an use every image-format GTK+ knows... and that are a lot.... )

hi walker
gtk_window_set_icon_from_file_(*window, *filename, *err) doesn't work any more with purebasic 4.10 is a bug?
This problems come up when I try to compile an unicode executable.

[walker]

no bug... gtk expects utf-8 formated strings.... the filename you pass isn't... that's something I had to learn too

see http://www.purebasic.fr/english/viewtopic.php?t=29302 and try that with gtk_window_set_icon_from_file_() it will work

Ok!
I try this:

Code: Select all

iconpath.s = GetPathPart(ProgramFilename()) + "Icon.png"
iconerror.l = 0
pathutf8.s = Space(255)
PokeS(@pathutf8,iconpath,#PB_UTF8)
gtk_window_set_icon_from_file_(Wpointer, @pathutf8, @iconerror)

where is the error?

Thanks

[walker]

first, if you use the flags parameter at PokeS, you have to add the length (or -1 for the whole length) otherwise the flag is treaten as length.....
second, import the needed function to pass the pseudo variable type p-utf8 and let PB translate the string into the desired format (see pseudotypes section in the manual)

here a working example:

Code: Select all

ImportC "/usr/lib/libgtk-x11-2.0.so"
  gtk_window_set_icon_from_file(*window,icon.p-utf8,*error)
EndImport

iconpath.s = GetPathPart(ProgramFilename()) + "Icon.png"
iconerror.l = 0
pathutf8.s = Space(255)
PokeS(@pathutf8,iconpath,-1,#PB_UTF8)
Wpointer=OpenWindow(#PB_Any ,0,0,200,100,"Icon-Test",#PB_Window_ScreenCentered|#PB_Window_SystemMenu)
gtk_window_set_icon_from_file(WindowID(Wpointer), PeekS(@iconpath), iconerror)
Repeat

Until WaitWindowEvent(1)=#PB_Event_CloseWindow

Thanks walker!
only one thing the import part is useless

[walker]

well.. not if you want to create an exe with unicode enabled..... but you can delete the line PokeS(...) in this example

Hi walker
Here work well without the include part. Please try yourself.

Thanks again!

[Beach]

Thanks for this code snippet! Works well here.

Is there a way to include the image with "IncludeBinary" and use it for the icon? No big deal if not, just curious.

[walker]

ohhhh... yesssss.. now I see what you mean..

Code: Select all

 iconpath.s = GetPathPart(ProgramFilename()) + "Icon.png"
iconerror.l = 0
pathutf8.s = Space(255)
PokeS(@pathutf8,iconpath,-1,#PB_UTF8)

Wpointer=OpenWindow(#PB_Any ,0,0,200,100,"Icon-Test",#PB_Window_ScreenCentered|#PB_Window_SystemMenu)
gtk_window_set_icon_from_file_(WindowID(Wpointer), PeekS(@pathutf8), iconerror) 

Repeat

Until WaitWindowEvent(1)=#PB_Event_CloseWindow

this way it will work without the Import....

@beach: yes, that would be possible.. but needs a little work as you can pass a GDKPixbuf to

Code: Select all

gtk_window_set_icon_(*window,*icon); 

if you include a png or whatever, you first have to create the PixBuf from it... I'd never tried this... but I will have a look how it would work...

Maybe this helps:

I asked for this some time ago and Freak posted a working example. It's great, though I'd like to load the icon from a file instead of using a data section.

I you'll get it working, please let us know. Thanks.
