space-expand | Pack widget expanding into space | `true` or `false` | 0.7.21
space-fill | Pack widget filling space | `true` or `false` | 0.7.21
block-function-signals | Block signal emissions from functions | `true` or `false` | 0.7.21
file-monitor | Emit signal when input file(s) change | `true` or `false` | 0.8.1
auto-refresh | Auto refresh when input file(s) change | `true` or `false` | 0.8.1
## Directives Some of these may have tag attribute equivalents.

action | Execute command on default signal | Shell command[1] |
action | Perform function on default signal | function:parameter[1] |
action signal="type" | Execute command on signal | Shell command[1] |
action signal="type" | Perform function on signal | function:parameter[1] |
action function="type" | Perform function on default signal | parameter[1] | 0.8.3

## Signals The default signal is "toggled", emitted when the state is changed. 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 | 0.8.1
save | Save widget data | Variable name | 0.8.1
clear | Remove all widget data | Variable name | 0.8.1
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. This widget's actions can be conditionally executed (based upon its active state) by prepending its contents with `if true` or `if false` although 0.8.3 introduced a dedicated condition attribute which may be more suitable. button, checkbox, colorbutton, comboboxentry, comboboxtext, combobox, edit, entry, eventbox, expander, fontbutton, frame, hbox, hscale, hseparator, list, menubar, menuitemseparator, menuitem, menu, notebook, pixmap, progressbar, radiobutton, separator, spinbutton, statusbar, table, terminal, text, timer, togglebutton, tree, vbox, vscale, vseparator, window,
