LockButton

GtkLockButton is a widget that can be used in control panels or preference dialogs to allow users to obtain and revoke authorizations needed to operate the controls. The required authorization is represented by a GPermission object. Concrete implementations of GPermission may use PolicyKit or some other authorization framework. To obtain a PolicyKit-based GPermission, use polkit_permission_new().

If the user is not currently allowed to perform the action, but can obtain the permission, the widget looks like this

and the user can click the button to request the permission. Depending on the platform, this may pop up an authentication dialog or ask the user to authenticate in some other way. Once the user has obtained the permission, the widget changes to this

and the permission can be dropped again by clicking the button. If the user is not able to obtain the permission at all, the widget looks like this

If the user has the permission and cannot drop it, the button is hidden.

The text (and tooltips) that are shown in the various cases can be adjusted with the "text-lock", "text-unlock", "tooltip-lock", "tooltip-unlock" and "tooltip-not-authorized" properties.

onPressedListeners void delegate(Button)[] onPressedListeners;: Undocumented in source.
addOnPressed void addOnPressed(void delegate(Button) dlg, ConnectFlags connectFlags): Warning GtkButton::pressed has been deprecated since version 2.8 and should not be used in newly-written code. Use the "button-press-event" signal. Emitted when the button is pressed.

addOnReleased void addOnReleased(void delegate(Button) dlg, ConnectFlags connectFlags): Warning GtkButton::released has been deprecated since version 2.8 and should not be used in newly-written code. Use the "button-release-event" signal. Emitted when the button is released.
callBackReleased void callBackReleased(GtkButton* buttonStruct, Button _button): Undocumented in source. Be warned that the author may not have intended to support it.
pressed void pressed(): Warning gtk_button_pressed has been deprecated since version 2.20 and should not be used in newly-written code. Use the "button-press-event" signal. Emits a "pressed" signal to the given GtkButton.
released void released(): Warning gtk_button_released has been deprecated since version 2.20 and should not be used in newly-written code. Use the "button-release-event" signal. Emits a "released" signal to the given GtkButton.
clicked void clicked(): Emits a "clicked" signal to the given GtkButton.

setRelief void setRelief(GtkReliefStyle newstyle): Sets the relief style of the edges of the given GtkButton widget. Three styles exist, GTK_RELIEF_NORMAL, GTK_RELIEF_HALF, GTK_RELIEF_NONE. The default style is, as one can guess, GTK_RELIEF_NORMAL.
getRelief GtkReliefStyle getRelief(): Returns the current relief style of the given GtkButton.
getLabel string getLabel(): Fetches the text from the label of the button, as set by gtk_button_set_label(). If the label text has not been set the return value will be NULL. This will be the case if you create an empty button with gtk_button_new() to use as a container.

setFocusOnClick void setFocusOnClick(int focusOnClick): Sets whether the button will grab focus when it is clicked with the mouse. Making mouse clicks not grab focus is useful in places like toolbars where you don't want the keyboard focus removed from the main area of the application. Since 2.4
getFocusOnClick int getFocusOnClick(): Returns whether the button grabs focus when it is clicked with the mouse. See gtk_button_set_focus_on_click(). Since 2.4
setAlignment void setAlignment(float xalign, float yalign): Sets the alignment of the child. This property has no effect unless the child is a GtkMisc or a GtkAlignment. Since 2.4
getAlignment void getAlignment(float xalign, float yalign): Gets the alignment of the child in the button. Since 2.4
setImage void setImage(Widget image): Set the image of button to the given widget. The image will be displayed if the label text is NULL or if "always-show-image" is TRUE. You don't have to call gtk_widget_show() on image yourself. Since 2.6
getImage Widget getImage(): Gets the widget that is currenty set as the image of button. This may have been explicitly set by gtk_button_set_image() or constructed by gtk_button_new_from_stock(). Since 2.6

getAlwaysShowImage int getAlwaysShowImage(): Returns whether the button will always show the image in addition to the label, if available.
getEventWindow Window getEventWindow(): Returns the button's event window if it is realized, NULL otherwise. This function should be rarely needed. Since 2.22
