The C version of looping over buttons and other items was weakly typed, causing runtime errors, and also C doesn't know how to iterate in abstract, so it was full of callbacks with user-defined data. Moving this to Rust, iteration is made of simple loops, and compile-time type-checked, at the cost of some more verbose code.
Remove pre-scaling of the bounds for the keyboard and its contents.
Calculate the scale factor based on the allocation and the desired width
and height of each keyboard, using the lower value of the horizontal and
vertical scale factors.
Apply scaling in the renderer and prepare to perform centering there.
This allows us to remove a lot of #ifdef's. Either we want to use
a config.h or we don't. Since we'll want it for e.g. optional gsound
support later on let's have it.
- use G_DECLARE_ and G_DEFINE_ macros
- move all data into ClassNamePrivate
- use _get_instance_private()
This should not introduce any functional changes or breakage.
Skipped two classes (EekKeyboard and EekboardContextService) for now in
order not to break the build.
These two classes are used in some very funky WIP code that tries to
circumvent encapsulation.
(Funky code is in eekboard/key-emitter.c and eekboard/eekboard-context-service.c)
EekGtkKeyboard is now a subclass of GtkWidget not EekKeyboard. Widget
creation is done as follows:
layout = eek_xkl_layout_new (...);
keyboard = eek_keyboard_new (layout, 640, 480);
widget = eek_gtk_keyboard_new (keyboard);
Broken Clutter support is temporarily disabled.
