We do not need to create a GtkTextIter to perform the comparison here as
that will require a number of validation steps that are extra work
compared to just discovering the GtkTextLine number directly.
We're mainly using this for icons that will never change contents or
size, and we're using a GtkScaler per such icon when on a hidpi setup,
so just avoid the two signal connections per icon.
Because otherwise when the file list is sorted "by name"
and the new name causes the file to be re-sorted to another
row, the selection stays in the old row which is now
occupied by a different file.
Fixed by keeping track of the renamed file and revealing
it in the "row-changed" signal handler, which gets emitted
after a file is renamed.
Fixes issue #948
This CSS snippet was supposed to only recolor the popover arrow but
ended up also recoloring the > arrow on modelbuttons that show a
submenu. Make the selector more specific.
The cairo pattern in use was simple enough, so just use a 2×1 or 1×2
texture to draw horizontal and vertical grid lines. This avoids a bunch
of cairo nodes (that can't be cached by the renderers).
Just queue_resize()ing the range itself doesn't work as it will just
re-allocate all the child widgets (i.e. just the trough) to its old
position and size.
We want to ensure all of the display cache entries are released in the
normal fashion before releasing the structures so that we can maintain
the invariant that cache_iter will always exist while in the cache.
This is happening for me when snapshotting small thumbnails in the file
chooser. The GtkScaler will scale the 1px height/width by 2, resulting
in nothing being drawn at all.
There is no reason for this to be a signal, since multiple handlers
don't make sense anyway. It was also broken because the scale needs to
know when a signal handler is added so it can update the value
representation.
Replace the signal with a set_format_value_func function which allows us
to do that.
Fixes#113
When loading a SVG icon from a gresource file only containing SVG icons,
but without having a SVG loader available in gdk-pixbuf, we would crash
when trying to eventually load the resource. Fix this by gracefully
handling this by simply failing to load the icon, while the first time
it happens, log a warning.
