Overview Open - Create or show/hide an overview window

With this function (hotkey Ctrl+O) you can create a new overview window or change the settings of an existing one. If an overview window has already been defined for the active view, it is opened with the existing settings - if not, the following dialog window is opened. Call the function once more to hide the overview window again. By using the keys Ctrl+O you can thus display and hide the overview window quickly.

The initial settings in this dialog can normally be confirmed without any changes (just click on the button or press the Enter key to open the overview window). The visible themes of the active view are automatically chosen for the overview window. If there were no themes visible in the view (image themes are excluded though), you must at least select one theme, before you can create an overview window.

Customize existing overview windows: You can modify the settings of an existing overview by calling the function Overview Open while pressing the Shift key. Thereby the dialog with the current settings of the overview is opened. At the settings Extent and Position the option Keep Current is added (in order to keep the overview extent and the window position unchanged).

The following settings can be changed in the dialog:

Permanent visibility is recommended if you are working with tables or several views at the same time and want the overview to be always available. If you click on an overview window or its title bar with the mouse pointer (e.g. for zooming to another extent) the corresponding view will be opened automatically.

Hint: If you want to define size and scale of the zones at the same time, you should consider the following: The view is always zoomed to the chosen scale. If you are panning with the cursor keys, the moving is done with the chosen width or height. If the window size of the view is too small for displaying the desired extent at the chosen scale, some areas of the view can't be displayed and will therefore be skipped when panning! Thus you must check, at which scale the zones can be displayed in the view. If you enter a scale at which a larger extent can be displayed, you can create overlapping areas when panning (e.g. an overlap of 50% if the visible extent is twice as wide or high as the defined zone extent).
