Parameters |
X0, Y0, X1, Y1 |
Required. Any four numeric values, locating the edges of the button in the window. To ensure consistent sizing, these parameters should be set using constants. A commonly-seen example follows: WinWd-2*BtnWd-2*Space, WinHt-Space, WinWd-BtnWd-2*Space, WinHt-BtnHt-Space |
Style | ||||||||||||
Required. Defines the button's appearance. A binary OR operation is done with a style number and the extra style bits shown in the following table. If the style number is 0, the button will have a normal appearance. If the style number is 1, the button will be a toggling button. Further style refinements are as follows:
|
Text | ||||||||||||
An optional expression for text to display on the button. Use the \GetPhrase function for multilingual applications. Will not display tab characters. |
||||||||||||
FocusID | ||||||||||||
An optional parameter from 0 to 32767 indicating the focus id. If Invalid or "0", no user interaction is permitted. | ||||||||||||
Font | ||||||||||||
An optional parameter specifying the font to use for text. Note that underlining is not supported. |
||||||||||||
ToggleVal | ||||||||||||
An output value, whose meaning depends on the button style. In a toggling button, ToggleVal is set to the toggle state of the button - 1 for pushed-in and 0 for not-pushed-in. For this button style, ToggleVal can also be used to change the state of the button programmatically. In a normal button, ToggleVal is purely an output parameter, indicating whether the button is currently being pressed. |
||||||||||||
Bitmap | ||||||||||||
An optional parameter specifying an image to use on the button. May be used with or without a value for the Text parameter. See example. | ||||||||||||
BitmapJustify | ||||||||||||
An optional numeric value, specifying how the image is aligned on the button. Possible values are as follows:
|
Comments: | None. |
Example:
Plain button, with monitoring of the current toggle state.
If WinButton(232, 148, 412, 100, 0 { normal appearance }, Concat("Press Me ", ButtonPresses) { label }, 1 { focus id enables button }, 0 { default system font }, ToggleVal { monitor state}); [ ButtonPresses++; ]
Button with image
MyImage = MakeBitmap("..\Bitmaps\warning symbol.bmp", 12, 9); If WinButton(232, 148, 412, 100, 0 { normal appearance }, Concat("Press Me ", ButtonPresses) { label }, 1 { focus id enables button }, 0 { default system font }, Invalid { no ToggleVal used }, MyImage { image displayed in the button}); [ ButtonPresses++; ]
