BBjFileChooser::getDropZoneVisible

Description

In BBj 16.0 and higher, this method specifies whether a client-side BUI BBjFileChooser should include a drop zone where users can drag-and-drop files.

Syntax

Return Value	Method
boolean	getDropZoneVisible()

Parameters

None.

Return Value

Returns true (1) if the drop zone was requested, false (0) if it was not.

Remarks

Files dropped to the drop zone are immediately uploaded to the server, reporting a BBjFileChooserApproveEvent . The OK/Cancel control buttons are not used.

Example

rem ' BBjFileChooser::getDropZoneVisible

dropzone = 0
message$ = "Client File Chooser"
if (msgbox("FILEOPEN or FILESAVE?",7+32,message$,"FILEOPEN","FILESAVE") = 1) then
    flags$ = $0004$
    title$ = "Client FILEOPEN"
    if (info(3,6) = "5") then
        dropzone = 1, dropzone$ = $0000$
        if (msgbox("Show a drop zone?",4+32,"Drop Zone") = 6) then
            dropzone$ = $0004$; rem ' checkbox flags = initially checked
            flags$ = $0006$; rem ' $0002$ = BBjFileChooser::setDropZoneVisible(1)
