Signals
The default signal is "child-exited", emitted when the terminal detects that the child has exited.
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 | Reactivate timer | Variable name | |
| disable | Deactivate timer | Variable name | |
| show | Show widget | Variable name | |
| hide | Hide widget | Variable name | |
| grabfocus | Grab input focus | Variable name | |
| refresh | Reload input data | Variable name | |
| clear | Reset terminal and re-execute command | Variable name | |
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 | |
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. There exists an equivalently named "background-tint-color" VTE property but it doesn't accept strings so it's converted by Gtkdialog.
This is a non-mandatory widget that requires libvte support be built into Gtkdialog at compile time.
This widget was introduced in version 0.8.1.
