Returns map view reference number or error.


Creates a new map view on the given window covering the area of the given control.
Use MapView.Release later to destroy the image view.

If you use a register (tab controls) on the window, be aware that the image view actually is in front of the register (tab controls). So you need to check in the script which register page is current and should show what image view. Or by a trigger you turn the visibility on and off.

Image view reference numbers are starting at 78000 and counting up for each new map view.

Not supported for MacOS 32-bit.
Does not work for Web Direct.

When creating on a card window, please pass reference to parent window or just 0 for front window. On MacOS you may need to pass delta y value to adjust position.

If you create a control on a new window, you may do window update command in your script first to have FileMaker actually build the window with controls and display it. A short script pause or using FM.RunScriptLater with 0.1 delay can help having all controls draw themselves. Then you can use this command to put our control on top. We use GetLayoutObjectAttribute() to query left, top, width and height and this gives empty value if control is not yet here.

Creation fails to pick the right window in case the window is selected by name and the window name is not unique. In that case better work with window reference numbers or just pass 0 for current front window.
