The "activate" signal is emitted when the user activates the entry with the Enter key. 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](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-button-press-event), [button-release-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-button-release-event), [configure-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-configure-event), [enter-notify-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-enter-notify-event), [leave-notify-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-leave-notify-event), [focus-in-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-focus-in-event), [focus-out-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-focus-out-event), [hide](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-hide), [show](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-show), [realize](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-realize), [key-press-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-key-press-event), [key-release-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-key-release-event), [map-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-map-event), [unmap-event](https://developer-old.gnome.org/gtk2/2.24/GtkWidget.html#GtkWidget-unmap-event) __Gtk3:__ [button-press-event](https://docs.gtk.org/gtk3/signal.Widget.button-press-event.html), [button-release-event](https://docs.gtk.org/gtk3/signal.Widget.button-release-event.html), [configure-event](https://docs.gtk.org/gtk3/signal.Widget.configure-event.html), [enter-notify-event](https://docs.gtk.org/gtk3/signal.Widget.enter-notify-event.html), [leave-notify-event](https://docs.gtk.org/gtk3/signal.Widget.leave-notify-event.html), [focus-in-event](https://docs.gtk.org/gtk3/signal.Widget.focus-in-event.html), [focus-out-event](https://docs.gtk.org/gtk3/signal.Widget.focus-out-event.html), [hide](https://docs.gtk.org/gtk3/signal.Widget.hide.html), [show](https://docs.gtk.org/gtk3/signal.Widget.show.html), [realize](https://docs.gtk.org/gtk3/signal.Widget.realize.html), [key-press-event](https://docs.gtk.org/gtk3/signal.Widget.key-press-event.html), [key-release-event](https://docs.gtk.org/gtk3/signal.Widget.key-release-event.html), [map-event](https://docs.gtk.org/gtk3/signal.Widget.map-event.html), [unmap-event](https://docs.gtk.org/gtk3/signal.Widget.unmap-event.html) ## 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 | | grabfocus | Grab input focus | Variable name | 0.8.1 | | refresh | Reload input data | Variable name | | | save[1] | Save widget data | Variable name | | | fileselect | Launch file selection dialog | Variable name | | | clear | Remove all widget data | Variable name | | | removeselected | Remove selected widget data | 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 | 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 | | 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. ## Notes ## 1. The save function will write the entry text to the output file if it is unique and non-null. This widget was introduced in version 0.7.21. ---
