[Glade-devel] Building Glade / error-message "attempting to create schema 'org.gtk.Settings.FileChooser' without a path"

[Roland Koebler]

Hi,

since Glade 3.18.3 now works here, here's an update about the issues I
found on Glade 3.16.0:

Solved: The self-compiled Glade looks much more familiar; I don't know
if it's still using a different theme, but I'm much happier with the used
theme now.

No change. (Still bad layout.)

No change. (Still doesn't work.)

No change (Still doesn't work.)
I'll create a bugreport for this, since e.g. the mouse-pointer changes to
a normal arrow after clicking on "Select widgets" on the toolbar, but
still a widget is added.

Maybe this has been resolved; but I have to test this more.

I currently don't know if this was solved; if this happens again with
Glade 3.18.3, I'll create a bugreport.

"Add Parent" now doesn't create an error-message, but after saving and
reloading the file, the contents of the added GtkScrolledWindow is
completely gone and it's not possible to add anything to the
ScrolledWindow again. So, I'll create a bugreport for this.

> - Missing "GtkImage" in Palette -> Miscellaneous:
>   In the Palette under "Miscellaneous", "GtkImage" is missing.
No change. I'll create a bugreport for this.

> - Missing "label"-property in GtkLinkButton Properties:
>   There is no way to modify the displayed contents of the linkbutton!
>   The only show "button", and this cannot be changed in Glade.
>   Workaround: Edit the GtkBuilder-XML-file directly.
No change. I'll create a bugreport for this.

>   I think "[ ] Add custom content" should be a radio-button instead of
>   a checkbutton, since it completely behaves like a radiobutton.
No change. I'll create a bugreport for this.

> - GtkButton Images are not shown in Glade:

No change. I'll create a bugreport for this.

Solved: Does not occur on self-compiled Glade 3.18.3.

No change. I'll create a bugreport for this.

No change. I'll create a bugreport for this.

I did not get such assertions yet; I'll create bugreports if I do again.
