C++ (Cpp) Surface_getArea Examples

Example #1

/**
 * Displays a message on-screen until either a mouse or keypress
 */
bool GfxSurface::displayText(const Common::String &msg, const Common::Point &pt) {
	// Set up a new graphics manager
	GfxManager gfxManager;
	gfxManager.activate();

Example #2

Example #3

Example #4

File: ringworld_logic.cpp Project: TomFrost/scummvm

}

Example #5

File: ringworld_dialogs.cpp Project: mauimauer/scummvm

void RightClickButton::highlight() {
	if (_savedButton) {
		// Button was previously highlighted, so de-highlight by restoring saved area
		g_globals->gfxManager().copyFrom(*_savedButton, _bounds.left, _bounds.top);

Example #6

	GfxDialog::setPalette();

	// Get the item to display

	// Wait for a press

	// Restore the old area
