The Zoom-Tool:

When activating the Zoom-Tool by clicking onto the zoom-tool button in the toolbar or by pressing the Insert key, the mouse cursor changes to the zoom-tool icon and you have several options:

•You can click with the left mouse button somewhere into the preview. This will zoom in by one level and center the preview at the point you had clicked. You can also press the Insert key, this will zoom in by one level using the current center of the preview.

•You can click with the left mouse button somewhere into the preview, hold the button down and drag the mouse. In this case a rubber band will appear. When you release the mouse button, the area covered by the rubber band will be zoomed into the preview.

•You can click with the right mouse button somewhere into the preview. This will zoom out by one level and center the preview at the point you had clicked.

•You can end the zoom tool mode by either pressing the ESC key or by clicking once again onto the zoom-tool button in the toolbar.

 

Special Keys:

•Ctrl + O: Open

•Ctrl + S: Save

•F1: Help

•F2: Print

•F3: Mail

•'g': Turn Grid on / off (only, if the grid button in the toolbar is enabled)

•'i': Info Dialog

•ENTER: enter a page number to preview

 

All keys listed above can be re-defined by your application, i.e. you can define by code, what key will cause a specific action.

 

Interactive Edition only:

•Tab: move the focus to the next enabled Control - if no Control currently owns the focus, the focus is set to the Control with the lowest Tab-ID

•Shift + Tab: move the focus to the previous enabled control

•ESC: remove the focus, if the focus is currently owned by an Interactive Text or an Interactive Form Field

 

The preview window can be customized in many ways: all keyboard accelerators can be redefind. You can hide buttons and button groups or even the whole toolbar. You can also hide the rulers and the statusbar, or specific controls of the statusbar. For details see "Management Functions" in the reference help files.

 

The closing of the document fires the event AfterDestroyWindow() (VCL: OnDestroyWindow(); DLL: VPE_DESTROYWINDOW) to your application, which can be used in several ways to have control over what is happening. For example you can disable menu entries and buttons in your application, which start report generation - so a report isn't generated a second time - and re-enable them after receiving this event.
