Toolbar

The attributes and functions explained on this page can be found in the Toolbar category.

The controls in the toolbar can be used to interactively perform various actions that are otherwise only accessible via the attributes. Each element can be shown or hidden. In addition, the entire toolbar can be adjusted in height or completely hidden.

The positioning of the elements in the toolbar is fixed and cannot be customized. If such adjustments are nevertheless necessary, you can hide the corresponding elements, implement them yourself with your own controls and place them on the History Control toolbar.

The available toolbar elements from left to right are:
