iwidgets::extbutton(1) [incr Widgets] iwidgets::extbutton(1)

iwidgets::extbutton - Extends the behavior of the Tk button by allowing a bitmap or image to coexist with text.

iwidgets::extbutton pathName ?options?

itk::Widget <- iwidgets::Extbutton

activebackground    activeforeground  bitmap
background          bd                cursor
disabledforeground  font              foreground
image               justify           relief      text

See the "options" manual entry for details on the standard options.

Name:	bitmapforeground
Class:	Foreground
Command-Line Switch:	-bitmapforeground
Configures the foreground color of the bitmap.

Name:	command
Class:	Command
Command-Line Switch:	-command
Associate a command with the extbutton. Simulates a Tk button's -command option. Invoked by either <1> events or by explicitly calling the public invoke() method.

Name:   defaultring
Class:  DefaultRing
Command-Line Switch:    -defaultring
Boolean describing whether the extbutton displays its default ring given in any of the forms acceptable to Tcl_GetBoolean. The default is false.

Name:   defaultringpad
Class:  Pad
Command-Line Switch:    -defaultringpad
Specifies the amount of space to be allocated to the indentation of the default ring ring given in any of the forms acceptable to Tcl_GetPixels. The option has no effect if the defaultring option is set to false. The default is 4 pixels.

Name:   imagePos
Class:  Position
Command-Line Switch:    -imagepos
Specifies the image position relative to the message text: n, ne, nw, s, se, sw, w, wn, ws, e, en, or es. The default is w.

Name:	ringBackground
Class:	Background
Command-Line Switch:	-ringbackground
Configures the background color of the default ring frame (if -defaultring is set to boolean true).

The extbutton extends the behavior of the atomic Tk button by allowing text and an image or bitmap to coexist. The user may use the -image or -bitmap options to specify an image as well as the -imagepos option to specify image position relative to the text. Note that the extbutton is not intended to be used without an image/bitmap. There will be an emtpy space next to the text if no image/bitmap is specified.

The iwidgets::extbutton command creates a new Tcl command whose name is pathName. This command may be used to invoke various operations on the widget. It has the following general form:

pathName option ?arg arg ...?

Each of the following methods are inherited from itk::Archetype. See that man page for details.

pathName cget
pathName component
pathName config
pathName configure

pathName invoke
Evaluates the command fragment associated with the -command option.
pathName flash
Simulates the Tk button's flash command.

package require Iwidgets 4.0
iwidgets::extbutton .eb -text "Bitmap example" -bitmap info \
  -background bisque -activeforeground red -bitmapforeground blue \
  -defaultring 1 -command {puts "Bisque is beautiful"}
