User interface (form)

When we create a new program with Delphi, it automatically creates, a main form which is the main window of our program.

This main form, at the beginning had :

• a default name : Form1 which can be changed with the name property.
• a title on the top bar. It's the caption of the form
• a icon : icon property
• a system menu




Several properties are fixed (border, starting position, width, height, etc...) but all of them can be changed with the object inspector or by code.




To add visible instances of objects we just have to choose it with the object browser and to click on the form area.




Creation

The FormCreate procedure is the procedure executed at the beginning of the project.

All the previous actions must be coded in this procedure :

• variable initialization
• default size
• default filepath
• etc...
