How to call a function?

[A]

@jamie

I know, however the issue is, assigning native icons to it programmatically. As of yet, a solution to this is unknown.

To see what I mean, this is an example of LibreOffice running on Linux Mint. Note the toolbar icons:

Now, this is an example of LibreOffice running on a different distribution, using the GTK+ stock icons. Note the toolbar icons:

For other applications, you can find examples of them using Windows' native icon set too.

The reason for this is to allow the application to blend into its native environments where it is being executed.

This is not done by having:
"Download for Linux Mint" - a version with Linux Mint's native icon set in the resource files.
"Download for Debian"      - a version with Debian's native icon set in the resource files.
"Download for Windows"  - a version with Windows' native icon set in the resource files.

No, it is done programmatically and I am trying to figure out how I can apply the same thing with my Lazarus application.

I know it is possible, as many Lazarus components do the same thing (change icons depending on Desktop Environment) - see DirEdit, ButtonPanel, etc.

Other applications that use the same sort of thing include:

- GIMP
- Kate Text Editor
- KeePass
- Geany
- Emacs
- Legacy Versions of Firefox
- And more...

That's what I'm trying to do.

I windows you have a API call "LoadBitMap" and with it, you can load predefined images

I do not know the calls for Linux , maybe the RTL has a compatible function ?

[jamie]

Looks like "LoadImage" is the more updated, that also will load the same

Just another thing about the stock image problem I've been having:
I've been searching online some more, as I will be for at least a year, and I've found that somebody has implemented code in Python using GTK's library trying to basically do the same thing as I am:
https://stackoverflow.com/questions/13659445/how-can-i-make-small-stock-icons-in-my-application

So this got me wondering - since Lazarus's applications use GTK (I presume, correct me if I'm wrong), will I be able to do what I am trying to do using the same technique? If so, does anybody have any insight as to how?

Thanks for your help.

PS: Jamie, unfortunately this is not what I need :/ However thanks for your help anyways.

Some more evidence of Gtk's libraries being used in Lazarus:

I wonder where I would program the design elements using Gtk's libraries?

Yes you are. GTK is the default except for windows, but you can also choose QT, or owner drawn or....
And note not all platforms provide system images like Windows does.

Cheers for the reply Thaddy,

I fear that I am quickly becoming the cancer of this forum with my persistence with regards to this problem.

Regardless, is there any way to implement Gtk+'s library via code (how Gtk+ is typically implimented - plain C) in Lazarus? Being so abstacted from the libraries actual code is really problematic for what I'm trying to do.

So, is there a way to either:

1). Program the form(s) in straight C and then somehow connect the Lazarus Object Pascal signals directly to this form?

2). Preferably, just somehow do this in Object Pascal:
https://stackoverflow.com/questions/13659445/how-can-i-make-small-stock-icons-in-my-application

Code: Pascal  [Select][+][-]

1. def _getCloseIcon(self):
2.         return gtk.image_new_from_stock(gtk.STOCK_CLOSE, gtk.ICON_SIZE_SMALL_TOOLBAR)
3.  

The fact that it has been done in Python makes me believe that it is possible to do it in Pascal (Laz).

Thanks a tonne for your help!

search your disk. in my windows installation I can see a gtk sample included in the folder D:\Lazarus\1.4.4\fpc\2.6.4\source\packages\gtk2\examples\gtk_demo that has everything you need to implement that feature for gtk your self.

Thanks Thaddy!

That was a really helpful example project and I have now managed to implement Gtk stock icons to my menubar!

Thanks for resolving my headache!
