Window resize issues in GTK3 build

[ScislaC]

The main Inkscape window is much wider than it should be and various interactions with the application (even moving the cursor around the interface), cause the size to grow.

Not sure if related, but there are a lot of these warnings show up in the console as well:

(inkscape:9591): GLib-GObject-WARNING **: /build/buildd/glib2.0-2.33.1/./gobject/gsignal.c:2455: signal `size_request' is invalid for instance `0x373b3f0'

These should be fairly easy to address. Instead of connecting to the "size-request" signal, we should use the gtk_widget_set_size_request function. See [1] for an example

Another window-width issue might come from the redesign of the GtkSpinButton widget to use a much wider "touchscreen friendly" horizontal layout.[2]

AFAICT this is triggered by the messages in the status bar (the random resizing - increase of the window width - doesn't happen when the status bar is hidden).

If the currently displayed message in the status bar is very short, the window width can be reduced, only to be increased whenever the message is replaced with a longer one.

This seems to cause absurd minimal widths for some of the docked dialogs (e.g. 'Object > Transform…).

Unclear to me yet what forces the minimal width of the 'Layers…' dialog to be much larger than needed.

I guess we may need to redesign some dialogs and toolbars to reduce the width. If we place GtkSpinButtons in a vertical layout, it would probably be neater.

Any thoughts?

Redesign proposals probably better be tracked in separate reports (yes, I do have the same first impression - unless GTK3 will offer a compact version of the spinbuttons, several elements of Inkscape's GUI might need to be redesigned).

I don't think this is the case, unfortunately. In fact, as I understand it, one of the main design goals for GTK+ 3 was touchscreen/tablet support. As such, the tiny up/down controls on spinbuttons were replaced by large, "proddable" +/- controls.

So, yes, I guess we should redesign accordingly!

Fixed statusbar resize issue in lp:inkscape r11497. We should open follow-up reports for individual dialogs that are demanding too much space.
