示例1: UpdatePosition
void UpdatePosition()
{
TextView textView = this.TextArea.TextView;
// PointToScreen returns device dependent units (physical pixels)
Point location = textView.PointToScreen(visualLocation - textView.ScrollOffset);
Point locationTop = textView.PointToScreen(visualLocationTop - textView.ScrollOffset);
// Let's use device dependent units for everything
Size completionWindowSize = new Size(this.ActualWidth, this.ActualHeight).TransformToDevice(textView);
Rect bounds = new Rect(location, completionWindowSize);
Rect workingScreen = System.Windows.Forms.Screen.GetWorkingArea(location.ToSystemDrawing()).ToWpf();
if (!workingScreen.Contains(bounds)) {
if (bounds.Left < workingScreen.Left) {
bounds.X = workingScreen.Left;
} else if (bounds.Right > workingScreen.Right) {
bounds.X = workingScreen.Right - bounds.Width;
}
if (bounds.Bottom > workingScreen.Bottom) {
bounds.Y = locationTop.Y - bounds.Height;
}
if (bounds.Y < workingScreen.Top) {
bounds.Y = workingScreen.Top;
}
}
// Convert the window bounds to device independent units
bounds = bounds.TransformFromDevice(textView);
this.Left = bounds.X;
this.Top = bounds.Y;
}
