Member Function Documentation

void ebl::win2d::buffer_resize ( uint  h,
uint  w,
bool  force = false 
) [protected]

Resize current buffer to given height and width.

Parameters:
forceIf true, will resize to any size, otherwise, will not accept to resize smaller than current size.
void ebl::win2d::clear ( ) [virtual]

Clears the window, but does not resize it, leaves it to the current size.

Reimplemented from ebl::win.

void ebl::win2d::repaint_pixmap ( ) [virtual]

Repaints the pixmap and updates window. This will take changes in drawing_mode into account.

void ebl::win2d::resize_window ( uint  h,
uint  w,
bool  force = false 
) [virtual]

Resize this window to hxw.

Parameters:
forceIf true, will resize to any size, otherwise, will not accept to resize smaller than current size.

Reimplemented from ebl::win.

void ebl::win2d::set_wupdate ( bool  ud) [virtual]

used to disable or enable updating of window, for batch displaying. this is useful to avoid flickering and speed up display.

Reimplemented from ebl::win.

void ebl::win2d::update_qimage ( uint  mode = 0) [protected]
Parameters:
modeThe channel(s) to display, 0: RGB, 1: R, 2: G, 3: B.
void ebl::win2d::update_window ( bool  activate = false) [virtual]

Refresh display of the window.

Parameters:
activateRaises the focus to this window if true.

Reimplemented from ebl::win.
