Will it be GTK2+ / Gnome?

[abligh]

It's gnome dialogs in KDE.

It's GNOME (or more accurately GTK) dialogs when compiling against wxWidgets WXGTK, MSW dialogs when compiling against wxWidgets WXMSW, Mac dialogs when compiling against wxWidgets WXMAC. You get the idea. If there was a WXQT (which there isn't, due to QT licensing problems) and we compiled against that, you'd get a KDE (or more accurately QT) file-open dialog. If you run the GTK app under KDE, the dialogs look like any other GTK app does running under KDE.

I'm sure the wxWidgets folks would be interested in patches to improve KDE friendliness provided there are no licensing issue involved.

Which licensing problems are those? Is wxWidgets LGPL or something? That still wouldn't stop them from releasing a WXQT under GPL. gnome file dialogs are a huge turn off for any app though, and the whole gnome philosophy is kind of hurting the Linux desktop across the board. And I really hate to see more applications, especially ones with graphics apps that are almost universally gtk on Linux.

wxWindows license version 3. LGPL with 3 exceptions, mainly for allowing binaries to be distributed without the demand to provide wx with it if it's unchanged, iirc. The other exceptions are backing that up. The license can be consulted directly.
One thing that this means is that we can't put LGPL code in - it would violate their license due to wxWidgets having that exception.

No, it wouldn't. Lack of manpower does. The license concerns can be alleviated through using a different source repository, or strict separation in directories.

That is a matter of opinion. For example I believe the same negative things to be true for KDE, and completely wrong for GNOME and GTK+. This is not the place to express such opinions.
The file dialog concerns are nonsense. They are fixed in GTK+-2.10, and the new dialog was introduced in 2.4. You really don't want to see what it was looking like pre-2.4. That's why wxGTK uses its own generic file dialog if gtk runtime version is not 2.4 or newer - it's considered so much more worse. GTK+-2.8 has it nice, 2.10 will have the location entry in the dialog, not behind a popup box, and will save settings, and not block on networked bookmarks, and other nice things.
