Learning Objectives
In this module you will learn how to
implement basic drag and drop
detect objects underneath another when dragging
implement dynamic mouse cursors (i.e. cursors that change depending on what is underneath them)
put an image into a control
load a file statically (at design time)
display information on the status bar
Module Description:
Summary
In this module you will be
develop a basic program that implements different drag and drop elements through the use of two image controls.
User Interface and Interaction
The application will behave like
ModuleDragDrop.zip
It consists of
Two PictureBox controls, each with a solid border and containing a different image.
Each PictureBox control can be dragged and dropped. In particular:
When the user clicks on a picture box,
the mouse cursor should change to a custom cursor.
Releasing the mouse button should return the cursor to default.
Each picture box should be visibly draggable and droppable
with smooth motion.
When a picture box is being dragged,
the status bar is updated to show its current coordinates
relative to the form.
When one picture box is dragged over another picture box,
the status bar should also indicate
which picture box is being dragged over which.
Implementation Details
The images in the PictureBoxes should be loaded from Resources,
and should be automatically embedded in the application at compile time.
