示例1: moveBrushPreview
void Editor::moveBrushPreview(const gfx::Point& pos, bool refresh)
{
ASSERT(m_sprite != NULL);
gfx::Point oldScreenPos = m_cursorScreen;
gfx::Point oldEditorPos = m_cursorEditor;
clearBrushPreview(false);
drawBrushPreview(pos, false);
gfx::Point newEditorPos = m_cursorEditor;
if (refresh) {
// Restore pixels
{
ScreenGraphics g;
SetClip clip(&g, gfx::Rect(0, 0, g.width(), g.height()));
forEachBrushPixel(&g, oldScreenPos, oldEditorPos, gfx::ColorNone, clearpixel);
}
if (cursor_type & CURSOR_THINCROSS && m_state->requireBrushPreview()) {
Brush* brush = get_current_brush();
gfx::Rect newBrushBounds = brush->bounds();
newBrushBounds.offset(newEditorPos);
m_document->notifySpritePixelsModified

// Save area and draw the cursor
