That test was cool in 2011, but hasn't been updated or used since then
because its features are now part of widget-factory and the inspector.
So let's remove it.
This library is meant to be the new CSS library that gets used from GDK,
GSK and GTK for string printing and parsing.
As a first step, move GtkCssProviderError into it.
While doing so, split it into GtkCssParserError (for critical problems)
and GtkCssParserWarning (for non-critical problems).
This will be used to let the inspector and other users
pick insensitive widgets again. For now, update all
callers to pass no flags, preserving the current
behavior.
The need of a specialised fixed layout container that can be placed into
a GtkScrolledWindow ceased to exist once GtkScrolledWindow gained the
ability to automatically interpose a GtkViewport when adding a child
that does not implement GtkScrollable.
All the other justifications that led to the existence of GtkLayout as a
separate widget from GtkFixed have been largely made irrelevant in the
20 years since its inception.
Add a ::show-peek-icon property and show a clickable
icon when it is set. Clicking it toggles the visibility
of the content. The same functionality is also accessible
via a context menu item.
This is a common feature of password entries.
Commit bd71e744d2 removed
gtk_box_pack_end(), but it added a gtk_container_add() with an
uninitialised widget, and the compiler is very unhappy about it.
The position child property is problematic, since it
requires us to emit notification for all children when
inserting a child early in the list of children.
Remove the property from all ui files.
as per efd3758f6a strcasecmp() is not a C
standard thing (not that we bothered including any header for it anyway)
and so this test failed to build on Windows with Microsoft Visual C.
Most of the code creating the two types of dialogs (open file,
choose folder) is the same. This refactors the common code into a
helper method. This also makes it easier to add other chooser types
for this test (e.g. save file).
This is way more complicated than it should be, because it requires
manually limiting the number of open file enumerators.
On the other hand, it exhaustively tests the items-changed emission of
all involved listmodels because those signals come in pretty much
randomly.
It's also 50% slower than the sync version, with the caeat that the sync
version only shows the UI after it's done loading, while this version
shows it right away.
This patch does multiple things:
1. Add a custom persistent per-row object.
2. Move all per-row API to that object. This means notifications are now
possible.
3. Add a "passthrough" construct-only property to the TreeListModel that
influences if the model returns these new object or passes through
the ones from the model.
This greatly simplifies the code needed to be written for widgetry,
because one can just connect the per-row object to the expanders that
expand and collapse rows.
As an added power feature, these objects can also be passed through
further models (like filter models).
It also adds kind of a hack to Adwaita to make the test look neat.
This is to go along with the newly introduced GdkDrop.
This commit includes the necessary updates to the X11, Wayland
and Broadway backends. Other backends have to be updated separately.
Instead of doing all handling manually in the ::event vfunc,
set up drag/multipress gestures on icon images, and implement
emission of ::icon-press/release and DnD there.
As a side effect, the GdkEvent field in ::icon-press/release
signals has been dropped. Callers that might be interested on it
may still use gtk_get_current_event*().
All of the four platform-dependent backends are enabled by default. It
is usually a good default because it requires users to explicitly choose
backends they want to use. Rules in meson.build also automatically
disable unavailable backends for macOS, Windows, Linux, so users on
these 3 major platforms don't have to manually disable things when
running meson commands.
However, meson.build doesn't do the same thing for other Unix-like
systems, which is acceptable but not ideal. To make it easier to build
GTK+ on these systems, the Linux case, which enables X11 and Wayland and
disables Win32 and Quartz, is made the default for all operating systems
that are not Windows or macOS.
This commit also changes most 'host_machine.system()' calls to os_*
variables, which are easier to read and less likely to be used wrongly.
