A Gnumeric worksheet can graphical user interface (GUI) elements, commonly called 'widgets', which can be tied to the data contents of worksheet cells. For example, users can add a slider widget which, when the position of the slider moves, alters the numeric value in a worksheet cell.
The current implementation of these widgets is incomplete. Some of the obvious configuration settings for these widgets do not exist and much of the functionality that these widgets should exhibit has not been implemented. Future versions of Gnumeric will complete these widgets and make them functional.
Widgets currently stay above all the other graphical elements because they use a different system to calculate their positions than the other graphical elements do. This will also be fixed in future updates.
Each of these elements can be added by selecting the appropriate icon on the object toolbar and using the thin cross-hair mouse pointer to place the element on the worksheet by clicking or by click-dragging with the primary mouse button. This process is explained in greater detail in Section 9.1.1 ― Adding Graphical Elements.
Each of these elements can be configured using the context menu and its Properties menu item, as explained in Section 9.1.5 ― Modifying Graphical Elements.
Each of these elements can be moved and resized on the worksheet, as explained in Section 9.1.3 ― Moving and Resizing Graphical Elements.
The stacking order, from the front to the back, which determines which widgets obscure each other, can be changed using the entries in the context menu, as explained in Section 9.1.7 ― Restacking Graphical Elements. However, as explained in the note above, the widgets do not currently stack under the other graphical elements.
Each of these elements can be deleted using the context menu and its Delete menu item, as explained in Section 9.1.8 ― Deleting Graphical Elements.
