Drag and Drop functions
The following functions are used to manage Drag and Drop:
Drag and Drop
Drag and Drop is used to transfer data between several controls with the mouse. This data can be moved between several controls found in the same application or in different applications.
Drag and Drop from the explorer
The Drag and Drop from the explorer consists in selecting one or more files in the Windows explorer and in transferring them into a control of a WINDEV window...
Automatic Drag and Drop
For some types of controls, WINDEV and WEBDEV offer an automatic management of Drag and Drop.
WINDEV: Example of programmed Drag and Drop
An iOS application with an iOS widget configuration can contain one or more iOS 14 widget windows...
Drag-and-drop operation set programmatically
The programmed Drag and Drop is used to entirely manage Drag/Drop between the different types of controls...
HTML 5: Example of programmed drag-and-drop management
To make a WEBDEV website more interactive, you have the ability to implement Drag and Drop in the pages.

The table items bound to the window controls are automatically updated with the values of these controls. the value of the WLanguage variables with the value of the window controls. The WLanguage variables bound to the page controls are automatically updated with the values of these controls. This operation is performed regardless of the state of the controls (grayed, inactive or invisible)....

GeometryCoveredBy (Function)
Determines if every point of geometry A lies inside or on the boundary of geometry B.
MultiLinestring2D (Variable type)
The MultiLinestring2D type can be used to store a collection of linestrings defined with 2D coordinates.
<PolygonGeo variable>.Intersection (Function)
Returns a geometry representing the intersection between a geographic polygon and another geometry.
<Polygon2D variable>.Intersect (Function)
Checks whether the intersection of a 2D polygon and another geometry does not result in an empty set.
