[Solved] Forcing left to right(LTR) GTK window

I have searched it in the web, can't find a good solution.
The problem is that in GTK+ windows is inverted while using Hebrew\Arabic or any RTL(right to left) language translation of GTK+.
I personally think that this is the way it should be.
However, I'm looking for a way(for developing) to force the GTK window be LTR(left to right) even know the user language align is RTL.
Is this thing possible? I can't find it at GTKWindow properties list.

It took me time, but eventually when I almost gave up I found the answer, thanks to this page.
Here it is if anyone want to know(or he searched in Google so much like me):
For all widgets:

Code:

gtk_widget_set_default_direction(GTK_TEXT_DIR_LTR);

For a specific:(If you program an IDE in GTK+(like MonoDevelop), please take a look at this so RTL users won't suffer- especially on the text area...)

Code:

gtk_widget_set_direction(GtkWidget *widget, GTK_TEXT_DIR_LTR);

* Edit: fixed the second code.
Works like a charm, but hard to found...

Thanx... I know it is very common problem for Hebrew/Arabic speakers or for developers which give a damn for those guys...

Look, I'm not a GTK expert. I'm just a guy who tried to solve a problem that have occurred to him, and have found the answer.

There is tree values:
GTK_TEXT_DIR_NONE - use the default direction setting.
GTK_TEXT_DIR_LTR - left to right direction for a specific widget.
GTK_TEXT_DIR_RTL - right to left direction for a specific widget.

First, this is work. If you don't believe me and you're LTR(left to right) speaker(At-list in your GTK/desktop setting), try to write this in your code, before you create the window(donn'o if it's work after):

Code:

gtk_widget_set_default_direction(GTK_TEXT_DIR_RTL);

This will flip your window to RTL. For example, if you have a menu bar on top, it will began from the right side and not from the left(like English).
But you do right I have a mistake in the second code I gave, see again the change I made above if you want to try it.
The first one over-set(ignore the user setting) the default widget direction only for the current process(i.e. widgets that their direction set to GTK_TEXT_DIR_NONE), and the second(above, not here) set the direction of a specific widget. Again, if you don't believe me, see this from first source:
