SftTabs/DLL 6.5 - Tab Control

GetDragInfo

Returns the drag & drop information while handling SFTTABSN_DRAGMOVE/SFTTABSN_DRAGDROP notifications.

C

void SftTabs_GetDragInfo(HWND hwndCtl, LPSFTTABS_DRAGINFO lpDragInfo);

C++

void CSftTabs::GetDragInfo(LPSFTTABS_DRAGINFO lpDragInfo) const;

Parameters

hwndCtl

The window handle of the tab control where tab reordering or drag & drop originated.

lpDragInfo

A pointer to a SFTTABS_DRAGINFO structure containing the drag & drop definitions. GetDragInfo uses this structure to return the current drag & drop information.

Comments

The GetDragInfo function returns the drag & drop information while handling SFTTABSN_DRAGMOVE/SFTTABSN_DRAGDROP notifications.

GetDragInfo and SetDragInfo can be used to disallow dragging to a target window (see SFTTABS_DRAGINFO, targetAllowed).
