};[/php]Class Information :

CForm(Constructor)
Parameters
callback :
Pointer to callback method, read more in callback methods section
objName :
Parameter is useless without the CFormManager class, which will be posted in a couple hours. Use to name the form object, set to NULL if you're not using a method to manage numerous forms, or plan to use a different system to identify them.
formX :
Form's default X position to render all controls and the form itself. Control structure contains offset X cords to this number. Thus the X cords in the Control structure are relative to the form's X position.
formY :
Form's default Y position to render all controls and the form itself. Control structure contains offset Y cords to this number. Thus the Y cords in the Control structure are relative to the form's Y position.
bgrLocalDir :
Pointer to a string which is null terminated. This string is used to load the background of the form. This only works locally. E.X, if the executable is placed in C:\program\program.exe and you pass "\\background.png" the class will load the image at C:\Program\Background.png. Be sure to include the \ character.
d3ddev :
A pointer to an initialized D3D Device.
font :
A pointer to a d3d font interface.
Description :
This is the constructor for the CForm class. It will initialize the private members needed to create controls and render the form. This must be called.
CreateControl
Parameters
name :
Controls name. You use this to modify it's properties using the built in callback. Refer to Callback information section.
text :
Text of Control. This can be the caption of a button, label, or default text in a textbox & password textbox.
type :
Refer to the ControlType enumerator defined in the CForm header. Specifies which kind of control you wish to create it as.
x :
Controls x position which is relative to the forms X position.
y :
Controls y position which is relative to the forms y position.
Command :
DWORD that specified the controls command code, read callback section for more information on this parameter.

Enabled :
Useless without CGUIManager class. More description on this paremeter will be posted at later time. For now ignore, and allow the compile set it to true, or set it to true yourself.
Description :
Creates a desired control for the form. This form will then be rendered when the render method within the class is called.
ProcessKey
Parameters
key :
Key which was pressed to be processed. '%' character will cause a deletion of the last character.
Description :
Processes a given key. This can cause several actions to occur depending on the active control. It may sometimes be ignored.
Callback
Parameters
Read callback section of this post for information on these parameters.
Description :
Read callback section of this post for information on these parameters.
MoveBy
Parameters
x :
Amount to change X coordination by.
y :
Amount to change Y coordination by.
Description :
Moves forms XY coordinations by a desired amount.
MoveTo
Parameters
x :
Set X coordination.
y :
Set Y coordination.
Description :
Moves forms XY coordinations to a desired position.
Render
Parameters
d3dSprite :
Pointer to initialized sprite interface.
Description :
Renders form.
Update
Ignore, useless without CGUIManager.
Callback Methods
A callback method has three parameters, the first is generally the command or the name of an object. Here's an example callback I write that should explain everything you need to know about them.
Form Init :
[php] mainForm = new CForm(FormCallback, "Form1",0,0, "FormDatatexturesdefaultForm.PNG", pd3ddev, d3dFont);
mainForm->CreateControl("cap1", "Login Window", Caption, 5, 5, 0);
mainForm->CreateControl("cap2", "Username:", Caption, 100, 80, 0);
mainForm->CreateControl("cap3", "Password:", Caption, 100, 110, 0);
mainForm->CreateControl("txtUsername", "Insert Username", Textbox, 170, 80, 0);
mainForm->CreateControl("txtPassword", "Insert Password", Password, 170, 110, 0);
mainForm->CreateControl("btnSubmit", "Submit", Button, 230, 130, BTN_SUBMIT);
mainForm->CreateControl("btnTwo", "Quit", Button, 300, 130, BTN_QUIT);
[/php]Callback :
[php]
void FormCallback(DWORD command, DWORD p1, DWORD p2) {
if(command == CONTROL_BUTTON_PRESS) {
if(!strcmp(mainForm->name, (char*)p1)) {
switch(p2) {
case BTN_QUIT:
tinit();
break;
case BTN_SUBMIT:
break;
}
}

}
}[/php]
Built-in callback :
[php]
Callback(DWORD Command, DWORD param1, DWORD param2) {
switch(Command) {
case CONTROL_APPEND_TEXT:
AppendText(GetControlIndex((char*)param1), (char*) param2);
break;
case CONTROL_GET_TEXT:
memcpy((void*)param2,
(void*)GetText(GetControlIndex((char*)param1)),
4);
break;
case CONTROL_SET_TEXT:
SetText(GetControlIndex((char*)param1), (char*) param2);
break;
case CONTROL_BUTTON_PRESS:
formCallback(CONTROL_BUTTON_PRESS, (DWORD)this->name, (DWORD)param1);
break;
}
}

[/php]
