* Now calls BApplication::HideCursor() on creation and ShowCursor() when it's
disconnected (so that you can still just call ShowCursor() to have it back, in case you want that). * Rewrote WindowScreen.h. * Cleanup, removed unused variables, renamed private methods. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17349 a95241bf-73f2-0310-859d-f6bbb57e9c96

This is the current version of WindowScreen. The main purpose of this object is to
|
||||
establish a direct connexion between application and graphic driver, to increase
|
||||
efficiency and abilities. The graphic driver architecture will overcome serious
|
||||
changes in the next release, consequently this could only be a preview version of
|
||||
the real WindowScreen API.
|
||||
|
||||
Nevertheless, compatibility will be insure in future releases FOR MOST OF THE API,
|
||||
through the use of a compatibility library (the new game library having a name
|
||||
different from "libgame.so"), or a compatibility class (the new WindowScreen class
|
||||
using a different name). Part of the API for which compatibility will not be insure
|
||||
after the Preview Release are specifically pointed out in the following declarations.

/******************************* Debugger API Notice ********************************
|
||||
Those three calls, and the debug_enable flag in the constructor, have been added to
|
||||
help debugging a WindowScreen application without a cross-developement platform or
|
||||
the use of serial debug output.
|
||||
rgb_color* ColorList();
|
||||
frame_buffer_info* FrameBufferInfo();
|
||||
graphics_card_hook CardHookAt(int32 index);
|
||||
graphics_card_info* CardInfo();
|
||||
|
||||
To use them, you need to :
|
||||
- enable the debug mode by setting the debug_enable flag of the constructor to "true".
|
||||
- register all threads that could be accessing the screen directly at any time. To do
|
||||
that, call RegisterThread after spawning the new thread and before resuming
|
||||
it (you should never draw from the Window thread itself, neither register it).
|
||||
- launch your application from Terminal. The GameKit will first swicth to another
|
||||
workspace before opening the WindowScreen. If you launch from workspace 0 [Alt-F1],
|
||||
it will choose the workspace 1 [Alt-F2]. For any other workspace, it will choose
|
||||
the previous one (for example, for workspace 3 (Alt-F4), it will choose workspace 2
|
||||
[Alt-F3]).
|
||||
void RegisterThread(thread_id thread);
|
||||
virtual void SuspensionHook(bool active);
|
||||
void Suspend(char* label);
|
||||
|
||||
Then :
|
||||
- You can use printf(...) anywhere to display informations that will be logged in the
|
||||
Terminal window. You can go back to the Terminal Window at any time (using the
|
||||
correct Alt-F?? key). Switching workspace will automatically suspend all the thread
|
||||
you registered and save the graphic context. Switching back to the WindowScreen
|
||||
workspace will restore everything and resume your application.
|
||||
- If you need to save and restore more states when your application is suspended and
|
||||
resumed, you can overwrite the ForceSwitchForDebug() method. This function is called
|
||||
with active == true just after suspending your app, and active == false just before
|
||||
resuming it.
|
||||
- You can suspend your application by calling the Debugger() method. This will also
|
||||
switch to the Terminal workspace. Then you can resume by just switchng back to the
|
||||
WindowScreen workspace (using the good Alt-F?? key). It's better not to call Debugger()
|
||||
with the WindowScreen locked.
|
||||
|
||||
In case of crash :
|
||||
- Use the safety short-cut : All the left modifiers (Ctrl, Shift, Option, Command, Alt
|
||||
or equivalents) of your keyboard and F12. That should send you back to 640x480, and
|
||||
the debugger terminal should be visible (and usable) if any.
|
||||
- Then, you can also switch to your Terminal workspace to check the last printf infos.
|
||||
- After you got (we hope) more information about your (or our :-) bug, quit the debugger
|
||||
window. Then you should be able to change your code and run your application again.
|
||||
In any case, check the Error() function immediately after the WindowScreen constructor.
|
||||
A bad error code will mean that the GameKit is in a inconsistent state, and then you
|
||||
have better to reboot your machine. If you don't wnat to reboot, you can also try to
|
||||
run your application in a different workspace.
|
||||
|
||||
It's far to be perfect, but we hope it will still help.
|
||||
|
||||
The Debug API will not be support after the Preview Release (replaced by the debug
|
||||
API in the new WindowScreen class).
