Instead of falling back to the role nick for both,
fall back to the class name for the name, and to
the empty string for the description. This makes
labels show up in Accerciser the same way they
did in GTK 3, and seems more useful to me than
the alternative.
Set the expected accessible role on the tagged entry
widget in the demo of the same name. Accessible tools
may decide to ignore widgets that have the wrong role,
so setting an appropriate role is important.
The ARIA spec determines the name and description of accessible elements
in a more complex way that simply mapping to a single property; instead,
it will chain up multiple definitions (if it finds them). For instance,
let's assume we have a button that saves a file selected from a file
selection widget; the widgets have the following attributes:
- the file selection widget has a "label" attribute set to the
selected file, e.g. "Final paper.pdf"
- the "download" button has a "label" attribute set to the
"Download" string
- the "download" button has a "labelled-by" attribute set to
reference the file selection widget
The ARIA spec says that the accessible name of the "Download" button
should be computed as "Download Final paper.pdf".
The algorithm defined in section 4.3 of the WAI-ARIA specification
applies to both accessible names (using the "label" and "labelled-by"
attributes), and to accessible descriptions (using the "description" and
"described-by" attributes).
Our Text implementation requires that we have
a GtkEditable with a delegate that is a GtkText
widget.
This change make the Text implementation work for
the custom widget in the tagged entry demo.
Implement the non-questionable parts of the Component interface
for accessibles which are widgets.
This does not include:
- global coordinates
- setters
- scrolling
- alpha, layers, zorder, and the like
Make right-aligned content work in resized columns.
There is currently no way to make a title right-aligned,
but we can still make it work correctly. This is a follow
up to 7eb0ae39c5.
Fixes: #3276
When resizing columns, we clip a shrunk column
on the right, so the separator disappears in that
case unless we put it on the left side of the other
column.
GLDEBUGPROC callback is defined with APIENTRY which is a windows
specific calling convention. That macro expands to nothing when building
on other platforms.
Fixes: #3268.
Ensure that the column resize cursor stays in place
for the duration of the resize drag. This is a bit
annoying, since the implicit grab can end up on the
header of a different column from the one we are
resizing, so just set the cursor on all column headers.
Make it so that for overlapping resize rectangles (with
very narrow columns), we prefer the narrow column, so you
can regrow a column after shrinking it all the way.

Ensure that we place the resize rectangle at the visible
right edge of the column, not where the allocation ends
(we clip the header drawing, after all).

Call SetCapture() explcitly for the (new) modal window so that we make the
modal window respond to mouse input, and also call SetCapture() to the parent
of the transient window that we are destroying so that mouse input capture is
returned to the parent window.
This attempts to fix the following:
* Upon creating a new modal window, the new modal window does not receive
pointer input unless one switches to another program and back
* Upon closing a transient window, the parent window that activated the
transient window does not receive pointer input unless one switches to
another and back
This reverts commit fc2008f2.
Turns out, we *don't* have code to maintain Z-order. Restacking
code is not doint that, it just enforces a few weird Z-order-related
behaviours.
Make sure that we get the state of the modal window properly, and send out the
corresponding notification signals.
This will ensure that we do not try to activate windows that should have become
inactivated due to it opening modal windows and render the program unresponsive
because we are not activating the correct window that is due to receive user
input.
