floatMdi
floatMdi();
The floatMdi method of the Form class floats an MDI child form; that is, it takes an MDI child form out of the MDI frame and allows it to be moved independently from the MDI frame (for example, on to another monitor on the PC). This method does nothing if the form is not docked or if the form is not an MDI child.
When floated, an MDI child form is positioned on the screen in the same position, except it is not a child restricted to the MDI frame.
The MDI child form is always on top of the MDI frame. To reposition the form programmatically, set the left and top properties, or use the Window class move method.
