Dragging a borderless Form....

[Qwick Miller]

I have my Form borders set to "none", because I am using a bitmap for my background. How do I drag the Form so the user can move the Form?

By catching a click and drag in whatever area works for you and setting your own window position based on the difference between the current mouse pos, and the mouse pos when you last checked. Christian Graus - Microsoft MVP - C++

Would you show me some code examples?

POINT lastDrag OnMouseDown { lastDrag = CurrentMousePosition (should be a parameter passed in to the event handler, but not this name ) } OnMouseMove { POINT moved = lastDrag - CurrentMousePosition lastDrag = CurrentMousePosition ::SetWindowPos(NULL, currentX + moved.X, currentY + moved.Y, 0, 0, SWP_NOSIZE | SWP_NOZORDER) } This is pseudocode.

Here's the solution: http://www.codeproject.com/csharp/CustomForms.asp[^] Point mouse_offset; .._MouseDown(..., System::Windows::Forms::MouseEventArgs * e) { mouse_offset = Point(-e->get_X(), -e->get_Y()); } .._MouseMove(..., System::Windows::Forms::MouseEventArgs * e) { if (e->Button == MouseButtons::Left){ Point mousePos = this->get_MousePosition(); mousePos.Offset(mouse_offset.X, mouse_offset.Y); this->set_Location(mousePos); } }
