For the MCU port, we need to proccess the image to save them in the binary
in a convenient format.
This patch start this work by trying to anaylyze what format should an image
be using, and saving it as a texture in the binary.
The current graphical backend and the C++ frontend are not yet supported
Avoid creating an intermediate array of items to free the graphics resources.
Instead call run-time function with the item tree as a parameter, which is traversed.
It's practically the same data structure that was previously created, except
that it is shared/global and has little holes for the dynamic tree items, but those are easy to skip.
As per commit 0c02f133f3daee146b805149e69bba8cee6727b2 in qtbase (qt6),
quit() on QCoreApplication on macOS calls [NSApp terminate], which will
not return to main. The latter however is documented behavior, and
sixtyfps-viewer for example relies on it.
The button bevel was rendered upside down, which happens due to some
weird double y-axis inversion, which goes away when passing the QWidget
pointer to the style. When using the Qt backend, we can do that.
When the PM_LayoutHorizontalSpacing pixel metric is negative, we're supposed to call
layoutSpacing() on the style. Until we have a detailed
overview over the controls, a default spacing is better than -1 :-)
Use the new fontdb API:
* When registering embedded fonts, we don't need to make a copy of the
embedded font data anymore.
* We don't have to mmap the font files ourselves anymore, fontdb can
do this now for us.
- The Tab must be drawn before the contents, because the style draws something under the active tab,
outside of its region
- Also set the QStyleOptionTab::HasFrame flag since we are in the equivalent of a QTabWidget
Some styles recompute the size based on the contents given in the QStyleOptionButton,
Some styles need to be given the icon in their content size. And this was not done properly
The font resolution function querying fontdb is fast now, so we can
always call it when rendering text. That way we don't need all the
indirection in the text_size(), etc. functions, we don't need an entry
in the item graphics cache for the font and we can avoid a lot of
property dependencies.
Unfortunately the text property was not included in the property dependency chain
for the cached Font.
This is fixed by delaying that with a getter function, but in the mid term
we should be able to remove this again once
femtovg learns lazy font resolution.
Set QStyle::State_Active conditional to whether the window is active,
which maps to Qt's active window concept and winit's has-focus (until we
render popups differently).
It was impossible to see which tab was the current tab.
Ensure that we set State_Active, like we do for the other styled controls.
Later, the active state should be tied to whether the window is "active" or not.
The metrics properties and the implementation of layout_info needs to
strictly reading cross-axis properties to avoid circular dependencies.
This patch applies a INT_MAX / 2 on the cross-axis to QStyle when
querying. Mostly the styles appear to just add/subtract margins, so this
value should not produce overflows while still providing an
approximation of "infinite" :)
Fixes#412
