示例1: IndexFromPoint
// Finds the index of the tab, which contains the given point.
int IndexFromPoint(int x, int y, bool *inXbutton=nullptr) {
Point point(x, y);
Graphics graphics(hwnd);
GraphicsPath shapes(data->Points, data->Types, data->Count);
GraphicsPath shape;
GraphicsPathIterator iterator(&shapes);
iterator.NextMarker(&shape);
ClientRect rClient(hwnd);
REAL yPosTab = inTitlebar ? 0.0f : REAL(rClient.dy - height - 1);
graphics.TranslateTransform(1.0f, yPosTab);
for (int i = 0; i < Count(); i++) {
Point pt(point);
graphics.TransformPoints( CoordinateSpaceWorld, CoordinateSpaceDevice, &pt, 1);
if (shape.IsVisible(pt, &graphics)) {
iterator.NextMarker(&shape);
if (inXbutton)
*inXbutton = shape.IsVisible(pt, &graphics) ? true : false;
return i;
}
graphics.TranslateTransform(REAL(width + 1), 0.0f);
}
if (inXbutton)
*inXbutton = false;
return -1;
}示例2: HitTest
/** \brief Test to see if we hit this object with a mouse click
* \param pos Click position
* \returns true it hit
*/
bool CPolyDrawable::HitTest(Gdiplus::Point pos)
{
// Transform the points
vector<Point> points;
for (auto point : mPoints)
{
points.push_back(RotatePoint(point, mPlacedR) + mPlacedPosition);
}
GraphicsPath path;
path.AddPolygon(&points[0], (int)points.size());
return path.IsVisible(pos) ? true : false;
