Primary changes:
Convert from dialog to an ordinary window, placing buttons according to data in keyboard.c
Character button text is now according to selected keyboard layout instead of system language.
Buttons will update* automatically when there is a layout switch (and when shift/capslock are pressed).
(Updating is most reliable when the keyboard is focused)
Removed keyboard dialog templates from resource files, they live on in keyboard.c
Secondary changes:
Support for font change, currently saved in registry is facename and height.
Additional registry load/save functions for strings to facilitate above change.
The dialog box at the startup of On-Screen Keyboard is displayed alongside with main window. While the Microsoft's OSK in XP is written in MFC and OSK is actually a mere window whereas our OSK is a dialog, the main dialog procedure call is superseded until the user does something with the warning dialog box on startup.
Just create a thread for it and handle the dialog box on startup in its own thread.
Rewrite LoadDataFromRegistry() and SaveDataToRegistry() as function helpers. With these, we'll be able to load and save data to registry on our choice.
200 ms would mean that the LEDs redraw each 0,2 second and this adds a slight delay. This can be seen if you press the Num lock key (for example) many times in a row and the LED resources won't update instantly. Therefore reducing the value of uElapse should significantly decrease the delay and the LEDs should update in a realistic way. Furthermore, before invalidating the LED resource check the toggle state of the keys.
- Replace the existing header files in favour to a pre-compiled header instead. Furthermore, move all the function prototypes in the pre-compiled header.
- As per the prototype definitions, LoadDataFromRegistry() and SaveDataToRegistry() mustn't accept any number of parameters.
- Rename rsrc.rc to osk.rc (main resource file) as most of user-mode applications name have their main resource as the same application's name anyways.
- When querying and saving the data to registry, use only one value, greatly reducing the bloat of variables (as per the Hermes Belusca's request on #1729 PR).
- Update the header description reflecting the official ReactOS Coding style guidelines.
