Description
When a user displays the context menu of a control, LabWindows/CVI generates an EVENT_CTRL_MENU event and sends the event to the callback function associated with the control.
Send the mouse coordinates in eventData1 and eventData2 to the following functions to get the cell, ID, or index location of the mouse-click.
- GetIndexFromPoint—Use for trees. Gets the tree index, cell, and area of the tree that corresponds to a coordinate.
- GetTableCellFromPoint—Use for tables. Gets the table cell.
- GetLegendItemFromPoint—Use for graphs and strip charts. Gets the trace index or plot handle for graphs or strip charts.
This event is swallowable. Return 1 to swallow EVENT_CTRL_MENU.
