We kept a backpointer from the Menu to its containing MenuBar, but it
was not used for anything so let's remove it.
Since all menus have the same font now, there's no need to track a
separate "title font".
This leaves menu applets running but invisible, and that's a regression
we need to take care of obviously. But not today, because it's getting
too late.
This patch begins the transition away from the global menu towards
per-window menus instead.
The global menu looks neat, but has always felt clunky, and there
are a number of usability problems with it, especially in programs
with multiple windows.
You can now call GUI::Window::set_menubar() to add a menubar to
your window. It will be specific to that one window only.
The previous names (RGBA32 and RGB32) were misleading since that's not
the actual byte order in memory. The new names reflect exactly how the
color values get laid out in bitmap data.
Because the z-order changes we not only need to recompute occlusions
but we also need to mark the screen area of the previous and new
highlighted window as dirty.
Fixes#5599
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
Also, only mark the menu bar item as opened if a menu was actually
opened through the menu bar.
These changes allow a menu to be used both in the menu bar as well
as a context menu.
Fixes#5469
A window repaint may change the alpha value, resulting in a different
hit test outcome. In those cases, re-evaluate the cursor hit testing
after a window was painted, and update the cursor if needed.
Tool windows are secondary windows with a smaller title bar. The sit on
the layer above normal windows, and cannot be minimized.
These are intended for complex yet non-modal interactions with the
content of a primary window, such as find/replace windows, property
windows, etc.
Minimum window size can now be customised and set at runtime via the
SetWindowMinimumSize WindowServer message and the set_minimum_size
LibGUI::Window method. The default minimum size remains at 50x50.
Some behind-the-scenes mechanics had to be added to LibGUI::Window to
ensure that the minimum size is remembered if set before the window is
shown. WindowServer sends a resize event to the client if it requests a
size on create that's smaller than it's minimum size.
We need to first deliver the mouse event and possibly the double click
event and record these facts. Then, we need to iterate all global
tracking listeners and deliver the mouse event (but not the double
click event) to any such listener, unless they already had these
events delivered.
Fixes#4703
I honestly don't know the internals of all this and what exactly is
going on, but this fixes compositing of the fullscreen window. By trial
and error I found that specifically m_invalidated_all needs to be set to
false, so it's probably different behaviour in prepare_dirty_rects(),
which depends on that...
Either way, the code composing all windows in non-fullscreen mode calls
Window::clear_dirty_rects() for each, so not doing that for the fullscreen
window as well seems like an oversight.
Fixes#4810.
We only cleared the area not covered by the backing bitmap if a
rendering rectangle intersected with the backing bitmap. But because
we are potentially calling the render function many times we need
to always clear the area not covered by the backing bitmap, whether
it intersects or not.
Fixes#5291
Merely moving a window shouldn't require re-rendering the window
frame anymore now that we cache the rendered frame in bitmaps. This
reduces CPU usage significantly when moving windows.
We weren't properly handling switching between having a shadow and
not having a shadow when switching themes. This allows an empty string
in the theme configuration for a shadow path, meaning no shadow should
be rendered.
Button now can handle middle and right clicks.
Added 2 new handlers in button class: on_right_click for Right mouse
button and on_middle_click for middle mouse button.
Added functionality to vertically maximize window with middle mouse
click on the maximize window button.
Also added a way to vertically maximize window by resizing window
height-wise lower than the maximum window height.
Since theme changes may change geometrics, which are also affected by
window shadows, we need to recompute occlusions as well as re-render
window frames.
