gtk-sharp 2.4.0.0 Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. Add Tooltips to your widgets. Tooltips are the messages that appear next to a widget when the mouse pointer is held over it for a short amount of time. They are especially helpful for adding more verbose descriptions of things such as in a toolbar. An individual tooltip belongs to a group of tooltips. A group is created by calling the constructor . Every tooltip in the group can then be turned off with and on with . To assign a tip to a particular , is used. Note: Tooltips can only be set on widgets which have their own X window. To add a tooltip to a that does not have its own , place the widget inside a and add a tooltip to that instead. The default appearance of all tooltips in a program is determined by the current Gtk theme that the user has selected. using Gtk; class ToolTipsExample { static void Main() { Application.Init(); Window win = new Window("Tooltips"); Button load_button, save_button; HBox hbox; Tooltips button_bar_tips; button_bar_tips = new Tooltips (); // Create the buttons and pack them into a Gtk.HBox hbox = new HBox (true, 2); win.Add(hbox); load_button = new Button ("Load a file"); hbox.Add(load_button); save_button = new Button ("Save a file"); hbox.Add(save_button); // Add the tips button_bar_tips.SetTip (load_button, "Load a new document into this window", "longer explanation"); button_bar_tips.SetTip (save_button, "Saves the current document to a file", "longer explanation"); win.ShowAll(); Application.Run(); } } Gtk.Object Method System.Void Allows the user to see your tooltips as they navigate your application.

Causes all tooltips in the tooltips group to become inactive. Any widgets that have tips associated with that group will no longer display their tips until they are enabled again with . Method System.Void Ensures that the window used for displaying the given tooltip is created. Ensures that the window used for displaying the given tooltip is created. (Applications should never have to call this function, since Gtk# takes care of this.) Method System.Void Adds a tooltip containing the specified message to the specified . an object of type an object of type an object of type Adds a tooltip containing the specified message to the specified . Constructor Internal constructor Pointer to the C object. This is an internal constructor, and should not be used by user code. Constructor Creates an empty group of tooltips.
