Signals
The default signal is "value-changed", emitted when the range value changes.
The "changed" signal is emitted when typing into the entry.
The "activate" signal is emitted when the user activates the entry with the Enter key.
For GTK+ 2.16 and later, the "icon-press" and "icon-release" signals are emitted when an activatable icon is pressed or released, but these signal names will be prefixed with either "primary-" or "secondary-" to indicate the source icon.
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

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 |
