See the GtkWidget widget properties[1].
The following custom tag attributes are available:
| Name | Description | Value | Since |
|---|---|---|---|
| milliseconds | Timer precision |
true or false
|
|
| interval[2] | Timer frequency | An unsigned integer value representing seconds or milliseconds | |
| block-function-signals | Block signal emissions from functions |
true or false
|
|
| 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 |
Some of these may have tag attribute equivalents.
| Name | Description | Contents | Since |
|---|---|---|---|
| variable | Variable name | ||
| variable export="false" | Variable name, not exported to shell | 0.8.3 | |
| input | Data input source | Shell command | 0.8.1 |
| input file | Data input source | Filename | 0.8.1 |
| sensitive | Active state |
true or false
|
|
| action | Execute command on default signal | Shell command | |
| action | Perform function on default signal | function:parameter | |
| action signal="type" | Execute command on signal | Shell command | |
| action signal="type" | Perform function on signal | function:parameter | |
| action function="type" | Perform function on default signal | parameter | 0.8.3 |
| action condition="type" | Execute command on default signal conditionally | Shell command | 0.8.3 |
| 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 |

The default signal is "tick", a custom signal emitted when the timer times-out.
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:
Gtk2: 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 Gtk3: 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
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 | 0.8.1 |
| hide | Hide widget | Variable name | 0.8.1 |
| refresh | Reload input data[3] | 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 |
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 |
| variable_is_true(argument) | Value of widget | Variable name | 0.8.5 |
| variable_is_false(argument) | Value of widget | Variable name | 0.8.5 |
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.
-
The "visible" (Gtk2, Gtk3) tag attribute will be required to hide the timer widget as it is visible by default.
-
The default precision is seconds using a default interval of 1 second.
-
The "sensitive" property i.e. its active state constitutes the data for this widget.
This widget was introduced in version 0.7.21.
