What's wrong here?
Code: Select all
OpenWindow(1, 1, 1, 200, 200, "")
CreateGadgetList(WindowID(1))
EditorGadget(1, 0, 0, 200, 200)
Buffer = gtk_text_view_get_buffer_(GadgetID(1))
gtk_text_buffer_set_text_(Buffer, "Some text here" + Chr(10) + "Some other line", Len("Some text here" + Chr(10) + "Some other line"))
gtk_text_buffer_create_tag_(Buffer, "style", "style", "PANGO_STYLE_ITALIC")
gtk_text_buffer_apply_tag_by_name_(Buffer, "style", 0, 10)
Repeat
Until WaitWindowEvent() = #PB_Event_CloseWindow

What does this tell me?
Doesn't PB submit the strings properly?

Why is it always me who doesn' get any answers?
Am I too stupid to ask proper questions?

No, you simply ask hard questions, which means we can't simply tell you to RTFM if we don't know the answers.
Your function call:
gtk_text_buffer_apply_tag_by_name_(Buffer, "style", 0, 10)
The function declaration:
void gtk_text_buffer_apply_tag_by_name(GtkTextBuffer *buffer, const gchar *name, const GtkTextIter *start, const GtkTextIter *end);
The error:
(purebasic.exe:11670): Gtk-CRITICAL **: gtk_text_buffer_apply_tag_by_name: assertion `start != NULL' failed
Conclusion:
Start can't be null (why I don't know), you passed 0 for start so an error is thrown.
Solution:
Pass another value for start.

As Trond pointed out, you have to pass a pointer to a GtkTextIter to the
procedure, not actual values (also for const GtkTextIter *end).
const GtkTextIter *start
I hate Gtk...

Hm, Wishmaster, have you solved the problem? Is it possible to see example code?
Thanks.

Unfortunately, I didn't figure out how to use those TextIters. In addition, PB 4.0 Beta 1 doesn't even start here on OpenSUSE 10.2 with the latest NVidia drivers.

I feel very sorry for you.
(Give Python + pygame a try... You'll be suprised.)
