Bug 316087 - Resizing columns is chaotic
|
||||
|
||||
* gtk/gtktreeprivate.h: add new member fields.
|
||||
|
||||
* gtk/gtktreeview.c (gtk_tree_view_init), (validate_row): set post
|
||||
validation flag,
|
||||
(gtk_tree_view_size_allocate_columns): rework the size allocation
|
||||
mechanism to only recalculate the expand values if the width of the
|
||||
widget, content or the column configuration has changed,
|
||||
(gtk_tree_view_size_allocate): move call to size_allocate_columns()
|
||||
to before the adjustment updates so the proper width is used after
|
||||
we updated it,
|
||||
(gtk_tree_view_button_press), (gtk_tree_view_motion_resize_column):
|
||||
use the column width minus the expand value for the resized width,
|
||||
(gtk_tree_view_move_column_after): update call to
|
||||
gtk_tree_view_size_allocate_columns().
|
||||
|
||||
* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_set_expand): set use
|
||||
resized width to FALSE.
|
||||
|
||||
* tests/Makefile.am:
|
||||
* tests/testtreecolumnsizing.c: new interactive test program
|
||||
for testing column resizing with different column configurations.
