Signals

The default signal is "clicked", emitted when the button has been activated (pressed and released).

The "file-changed" signal is emitted if file-monitor is true and the input file being monitored has changed.

The following signals are connected-up for all widgets:

button-press-event, button-release-event, configure-event, enter-notify-event, leave-notify-event, focus-in-event, focus-out-event, hide, show, key-press-event, key-release-event, map-event, unmap-event

Functions

The following functions can be performed upon this widget by any widget capable of emitting signals:

Type Description Parameter Since
enable Sensitise widget Shell variable name
disable Desensitise widget Shell variable name
show Show widget Shell variable name 0.8.1
hide Hide widget Shell variable name 0.8.1
activate Activate widget Shell variable name 0.8.1
grabfocus Grab input focus Shell variable name 0.8.1
refresh Reload input data Shell variable name 0.7.21

The following general functions can be performed by any widget capable of emitting signals:

Type Description Parameter Since
command Execute command Shell command
exit Exit dialog A value for the EXIT shell variable
closewindow Close dialog Shell variable name
launch Launch dialog Shell variable name
presentwindow Present dialog Shell variable name 0.8.1

Notes

1. The existing "image-position" GTK+ property -- normally only applicable to stock buttons -- has been extended to apply to all Gtkdialog buttons.

2. The existing "homogeneous" GTK+ property -- applicable to the hbox and vbox -- can be used here to effect the box inside the button when including an image and a label.

3. Theme icons default to 20 and do not scale or refresh (the "theme-icon-size" custom tag attribute can be used to request a size).

4. Stock icons default to GTK_ICON_SIZE_BUTTON and do not scale or refresh (the "stock-icon-size" custom tag attribute can be used to request a size).
