# InForm
|
||
|
|
A GUI engine and WYSIWYG interface designer for QB64
|
||
|
|
|
||
|
|
## Event-driven QB64 programs
|
||
|
|
InForm's main goal is to generate event-driven QB64 applications. This means that you design a graphical user interface with interactive controls and then write the code to respond to such controls once they are manipulated.
|
||
|
|
|
||
|
|
## Workflow
|
||
|
|
After your form looks the way you want it to, click File -> Save to export its contents and generate a .bas source file. Three files are output:
|
||
|
|
* **.frmbin**
|
||
|
|
the binary form that can be later edited.
|
||
|
|
|
||
|
|
* **.frm**
|
||
|
|
a representation of the generated form in QB64 code. This can be edited in QB64 or any text editor later, if you want to adjust fine details.
|
||
|
|
|
||
|
|
* **.bas**
|
||
|
|
the actual program you will add your code to.
|
||
|
|
|
||
|
|
### You add code to respond to events:
|
||
|
|
* *Click*
|
||
|
|
* *MouseEnter/MouseLeave* (hover)
|
||
|
|
* *FocusIn/FocusOut*
|
||
|
|
* *MouseDown/MouseUp* (events preceding a Click)
|
||
|
|
* *KeyPress*
|
||
|
|
* *TextChanged* (for text box controls)
|
||
|
|
* *ValueChanged* (for track bars, lists and dropdown lists)
|
||
|
|
|
||
|
|
### There are also events that occur in specific moments, to which you can respond/add code:
|
||
|
|
* *BeforeInit*, triggered just before the form is shown.
|
||
|
|
* *OnLoad*, triggered right after the form is first shown.
|
||
|
|
* *BeforeUpdateDisplay*, triggered everytime the form is about to be repainted.
|
||
|
|
* *BeforeUnload*, triggered when the user tries to close the program, either via clicking the window's X button, right click in the task bar -> Close or with Alt+F4 (Windows only).
