action condition="type" Perform function on default signal conditionally function:parameter 0.8.3
action signal="type" condition="type" Execute command on signal conditionally Shell command 0.8.3
action signal="type" condition="type" Perform function on signal conditionally function:parameter 0.8.3

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, realize, 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 Variable name
disable Desensitise widget Variable name
show Show widget Variable name 0.8.1
hide Hide widget Variable name 0.8.1
activate Activate widget Variable name 0.8.1
grabfocus Grab input focus Variable name 0.8.1
refresh Reload input data Variable name 0.7.21

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

Type Description Parameter Since
break Break out of actions list None 0.8.3
command Execute command Shell command
exit Exit dialog A value for the EXIT variable
closewindow Close dialog Variable name
launch Launch dialog Variable name
presentwindow Present dialog Variable name 0.8.1

Conditions

The following conditions can be used within the condition attribute of action directives:

Type Description Argument Since
active_is_true(argument) Active state of toggle widget Variable name 0.8.3
active_is_false(argument) Active state of toggle widget Variable name 0.8.3
command_is_true(argument) Output of shell command Shell command 0.8.3
command_is_false(argument) Output of shell command Shell command 0.8.3
file_is_true(argument) Contents of a file Filename 0.8.3
file_is_false(argument) Contents of a file Filename 0.8.3
sensitive_is_true(argument) Sensitive state of widget Variable name 0.8.3
sensitive_is_false(argument) Sensitive state of widget Variable name 0.8.3
visible_is_true(argument) Visible state of widget Variable name 0.8.3
visible_is_false(argument) Visible state of widget Variable name 0.8.3

true means "true", "yes" or a non-zero value, false means "false", "no" or zero, therefore the shell command is expected to echo one of these values to stdout.

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).
