I just pushed the wip/baseline branch to git. It contains the initial steps towards adding baseline alignment in gtk+, by extending the size request and size allocation framework with: * A way to report a baselines corresponding to the minimum and natural heights * A way to allocate the baseline of a child widget in a baseline aware container * A way to flag widgets that they want to be baseline aligned
It also contains baseline support for label, button, alignment and horizontal boxes which works well enough for this test: http://people.gnome.org/~alexl/baseline.png I started working on the vertical box implementation, where we would align the baseline to the baseline of the first child that had GTK_ALIGN_BASELINE valign. This is useful for e.g. layouts like this: +-----------+------------------+ | | [IMG] | | | [IMG] | | Label....|...[Entry] [IMG] | | | | | +------------------+ | | | ......... Where we want the label in the left to align with the first text in the vbox on the right side. Conceptually this doesn't seem very hard, and i got the size request part done easily. However, the size_allocate() implementation for the case where a particular child widget is supposed to be on a specific position is very complicated due to all the complexity of boxes (pack start/end, homogenous, natural distribution of height, etc) so I gave up for now. However, I think implementing baseline support for things like entries, rows-in-GtkGrid, GtkButtonBox, etc should be pretty easy and might be an interesting excercise for other people who try out this branch. _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-devel-list
