XPStandardWidgets - THEORY OF OPERATION
The standard widgets are widgets built into the widgets library. While you
can gain access to the widget function that drives them, you generally use
them by calling XPCreateWidget and then listening for special messages,
etc.
The standard widgets often send mesages to themselves when the user
performs an event; these messages are sent up the widget hierarchy until
they are handled. So you can add a widget proc directly to a push button
(for example) to intercept the message when it is clicked, or you can put
one widget proc on a window for all of the push buttons in the window.
Most of these messages contain the original widget ID as a parameter so you
can know which widget is messaging no matter who it is sent to.

{___________________________________________________________________________
* MAIN WINDOW
___________________________________________________________________________}
{
The main window widget class provides a "window" as the user knows it.
These windows are dragable and can be selected. Use them to create
floating windows and non-modal dialogs.
}
CONST
xpWidgetClass_MainWindow = 1;
{
Main Window Type Values
These type values are used to control the appearance of a main window.
}
{ The standard main window; pin stripes on XP7, metal frame on XP 6. }
xpMainWindowStyle_MainWindow = 0
;
{ A translucent dark gray window, like the one ATC messages appear in. }
xpMainWindowStyle_Translucent = 1
;
{
Main Window Properties
}
{ This property specifies the type of window. Set to one of the main window }
{ types above. }
xpProperty_MainWindowType = 1100
;
{ This property specifies whether the main window has close boxes in its }
{ corners. }
xpProperty_MainWindowHasCloseBoxes = 1200
;
{
MainWindow Messages
}
{ This message is sent when the close buttons are pressed for your window. }
xpMessage_CloseButtonPushed = 1200
;
{___________________________________________________________________________
* SUB WINDOW
___________________________________________________________________________}
{
X-plane dialogs are divided into separate areas; the sub window widgets
allow you to make these areas. Create one main window and place several
subwindows inside it. Then place your controls inside the subwindows.
}
CONST
xpWidgetClass_SubWindow = 2;
{
SubWindow Type Values
These values control the appearance of the subwindow.
}
{ A panel that sits inside a main window. }
xpSubWindowStyle_SubWindow = 0
;
{ A screen that sits inside a panel for showing text information. }
xpSubWindowStyle_Screen = 2
;
{ A list view for scrolling lists. }

}
{ This property specifies the type of window. Set to one of the subwindow }
{ types above. }

{___________________________________________________________________________
* BUTTON
___________________________________________________________________________}
{
The button class provides a number of different button styles and
behaviors, including push buttons, radio buttons, check boxes, etc. The
button label appears on or next to the button depending on the button's
appearance, or type.
The button's behavior is a separate property that dictates who it hilights
and what kinds of messages it sends. Since behavior and type are
different, you can do strange things like make check boxes that act as push
buttons or push buttons with radio button behavior.
In X-Plane 6 there were no check box graphics. The result is the following
behavior: in x-plane 6 all check box and radio buttons are round
(radio-button style) buttons; in X-Plane 7 they are all square (check-box
style) buttons. In a future version of x-plane, the xpButtonBehavior enums
will provide the correct graphic (check box or radio button) giving the
expected result.
}
CONST
xpWidgetClass_Button = 3;
{
Button Types
These define the visual appearance of buttons but not how they respond to
the mouse.
}
{ This is a standard push button, like an "OK" or "Cancel" button in a dialog }
{ box. }

;
{ A check box or radio button. Use this and the button behaviors below to }
{ get the desired behavior. }
xpRadioButton = 1
;
{ A window close box. }
xpWindowCloseBox = 3
;
{ A small down arrow. }
xpLittleDownArrow = 5
;
{ A small up arrow. }
xpLittleUpArrow = 6
;
{
Button Behavior Values
These define how the button responds to mouse clicks.
}
{ Standard push button behavior. The button hilites while the mouse is }
{ clicked over it and unhilites when the mouse is moved outside of it or }
{ released. If the mouse is released over the button, the }
{ xpMsg_PushButtonPressed message is sent. }
xpButtonBehaviorPushButton = 0
;
{ Check box behavior. The button immediately toggles its value when the }
{ mouse is clicked and sends out a xpMsg_ButtonStateChanged message. }
xpButtonBehaviorCheckBox = 1
;
{ Radio button behavior. The button immediately sets its state to one and }
{ sends out a xpMsg_ButtonStateChanged message if it was not already set to }
{ one. You must turn off other radio buttons in a group in your code. }
xpButtonBehaviorRadioButton = 2
;
{
Button Properties
}
{ This property sets the visual type of button. Use one of the button types }
{ above. }
xpProperty_ButtonType = 1300
;
{ This property sets the button's behavior. Use one of the button behaviors }
{ above. }
xpProperty_ButtonBehavior = 1301
;
{ This property tells whether a check box or radio button is "checked" or }
{ not. Not used for push buttons. }
xpProperty_ButtonState = 1302
;
{
Button Messages
These messages are sent by the button to itself and then up the widget
chain when the button is clicked. (You may intercept them by providing a
widget handler for the button itself or by providing a handler in a parent
widget.)
}
{ This message is sent when the user completes a click and release in a }
{ button with push button behavior. Parameter one of the message is the }
{ widget ID of the button. This message is dispatched up the widget }
{ hierarchy. }
xpMsg_PushButtonPressed = 1300
;
{ This message is sent when a button is clicked that has radio button or }
{ check box behavior and its value changes. (Note that if the value changes }
{ by setting a property you do not receive this message!) Parameter one is }
{ the widget ID of the button, parameter 2 is the new state value, either }
{ zero or one. This message is dispatched up the widget hierarchy. }
xpMsg_ButtonStateChanged = 1301
;
{___________________________________________________________________________
* TEXT FIELD
___________________________________________________________________________}
{
The text field widget provides an editable text field including mouse
selection and keyboard navigation. The contents of the text field are its
descriptor. (The descriptor changes as the user types.)
The text field can have a number of types, that effect the visual layout of
the text field. The text field sends messages to itself so you may control
its behavior.
If you need to filter keystrokes, add a new handler and intercept the key
press message. Since key presses are passed by pointer, you can modify the
keystroke and pass it through to the text field widget.
WARNING: in x-plane before 7.10 (including 6.70) null characters could
crash x-plane. To prevent this, wrap this object with a filter function
(more instructions can be found on the SDK website).
