- WEBDEV: The controls affected by the automatic Drag and Drop
- Configuring the default Drag and Drop
For some types of controls, WINDEV and WEBDEV propose an automatic management of Drag and Drop. No specific programming is required. In the control description, all you have to do is specify that Drag and Drop must be supported. You must not: - call the functions for managing the Drag and Drop through programming,
- enable the codes for managing the Drag and Drop in the processes of the controls.
Otherwise, the automatic management will be disabled: therefore, Drag and Drop must be managed through programming. This page presents: WINDEV: The controls affected by the automatic Drag and Drop In WINDEV, the automatic Drag and Drop is available for the following controls: - Edit control,
 Novedad versión 2024control "Text tokens" input system (Drag and Drop tokens). - List Box control,
- ListView control,
- Table control,
- TreeView control.
Special cases: Drag and Drop between two Table controls:
To perform an automatic Drag and Drop between two Table controls: - The number of columns must be identical. The content of column 1 of source Table control will be copied into column 1 of target Table control, idem for column 2, ...
- The columns can have different names.
- The type of columns can be different. CAUTION: In this case, the data can be altered or lost during the transfer (automatic conversions). In this case, we recommend that you use the drag-and-drop operations set programmatically.
Moves allowed between controls: | | | | Source element | Target element | Action performed |
|---|
| control Table file | Table control populated programmatically | The rows selected in the source Table control are copied into the target Table control. | | List Box control populated programmatically | The rows selected in the Table control are copied into the target List Box control: the data found in the columns is separated by tabulations. | | Edit control | - on a simple edit control, only the first element is copied. The elements found in the different columns are separated by tabulations.
- on a multiline edit control, all elements are copied (separated by a CR). The elements found in the different columns are separated by tabulations.

Remark: These controls can be: - in the same window,
- in another window of the application (Multi-windowing or MDi),
- in a window of another WINDEV application.

Remark: At this time, only Firefox and Chrome fully support Drag and Drop via HTML 5. If the new versions of the different browsers include the management of Drag and Drop via HTML 5, this feature will be automatically supported by WEBDEV. Configuring the default Drag and Drop For the controls that propose the automatic Drag and Drop, this feature is configured in the "Details" screen of control description. The "Is source" option is used to define the control as "Source" of Drag and Drop. The user will be able to select the content of the control and to move it to another control for example. The "Is target" option is used to define the control as "Target" of Drag and Drop. This control will be able to receive any object "dropped" by the user. The two options can be selected simultaneously. Remarks: - If only the "Is source" option is checked for the control, the action performed by default will be a copy. The cut is not allowed.
- If the "Is source" and "Is target" options are checked for the control, the action performed by default will be a cut. Press the Ctrl key simultaneously to perform a copy.
 In TreeView controls, it is possible to: - copy or move a root element before or after an element of the TreeView control.
- copy or move an element to a sub-level of the TreeView control.
- copy or move a single element or an element and all its children.
