Making a Control Moveable
Here we demonstrate the moveable controls capability of Qcodo, also known as
"Drag and Drop".
All
QControls are capable of being moved. However, only
QLabel and
QPanel
controls are capable of being "move handles". A "move handle" is anything that you can click
which can begin execution of a move. For example, in a standard GUI (e.g. Windows
or the Mac OS), you cannot just click anywhere on a window to make the window move. You
can only click on a window's
Title Bar to get that window to move. So while
the window, itself, is a moveable object, the window's
Title Bar is the "move
handle". And in this case, the "move handle" is targetted to move itself as well as the
window it is connected to.
The
QLabel and
QPanel controls have an
AddControlToMove method defined
on it, which takes in a
QControl as a parameter. Making this call will cause your
QLabel or
QPanel to become a "move handle". And the
QControl you pass
in will be added as a control that will be moved by it.
In this example, we define a simple
QPanel, and we add itself as a moveable control so
that you can click on the panel and move it around.
