Result

Description

Creates a new drop area on the given window covering the area of the given control.
Use DragDrop.Release later to destroy the drop area.
If you use a register on the window, be aware that the drop area actually is in front of the register. So you need to check in the script which register page is current and should get the dropped files.
Drag & Drop reference numbers are starting at 31000 and counting up for each new drop area.

Added Windows support for MBS Plugin 8.1 for FileMaker 16 or newer.
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 GetControl() 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.

Examples

Creates a new drop area:

Set Variable [ $$dropview ; Value: MBS("DragDrop.CreateWithControl"; Get(WindowName); "drop") ]
Set Variable [ $result ; Value: MBS( "DragDrop.RegisterDropTypes"; $$dropview; "file") ]
Set Variable [ $result ; Value: MBS( "DragDrop.SetDragActionHandler"; $$dropview; Get ( FileName ); "DragAction") ]
Set Variable [ $result ; Value: MBS( "DragDrop.SetCursor"; $$dropview; 1) ]
Set Variable [ $result ; Value: MBS( "DragDrop.SetImage"; $$dropview; DragTest::DropLogo) ]
