Events The Assign Action dialog lists all of the available Events. To assign a macro to an event: 1. Select the event 2. Click Macro... 3. Browse to and select the macro you want to assign 4. Click OK Parameters The occurrence of a particular event is not always enough for an appropriate response. Additional information may be required. For example, to process a mouse click, you may need the screen position where the mouse button was pressed. In OpenOffice.org Basic, you can use object parameters to provide more information about an event to a procedure, for example: Sub ProcessEvent(Event As Object) End Sub The structure and properties of the Event object depend on the type of event that triggers the procedure call. Regardless of the type of event, all objects provide access to the relevant control element and its model. The control element can be reached using Event.Source and its model using Event.Source.Model. You can use these properties to trigger an event within an event handler. Mouse Events OpenOffice.org Basic recognizes the following mouse events: Mouse moved user moves mouse Mouse moved while key pressed user drags mouse while holding down a key Mouse button pressed user presses a mouse button Note – This event is also used for notifying requests for a popup context menu on the control. In this case, the member PopupTrigger of the event passed to your macro function will be TRUE. In particular, if such a request is made by pressing the right mouse button on the control, the event will be fired twice: once for the popup menu request, and once for the real mouse event. If you are interested in only the mouse click, your macro should ignore all calls where PopupTrigger is TRUE. Mouse button released user releases a mouse button Mouse outside user moves mouse outside of the current window The structure of the associated event objects is defined in the com.sun.star.awt.MouseEvent structure which provides the following information: 158 OpenOffice.org 3.2 BASIC Guide · March 2010
Buttons (short) X (long) Y (long) button pressed (one or more constants in accordance with com.sun.star.awt.MouseButton) X-coordinate of mouse, measured in pixels from the top left corner of the control element Y-coordinate of mouse, measured in pixels from the top left corner of the control element ClickCount (long) number of clicks associated with the mouse event (if OpenOffice.org can respond fast enough, ClickCount is also 1 for a double-click because only an individual event is initiated) The constants defined in com.sun.star.awt.MouseButton for the mouse buttons are: LEFT RIGHT MIDDLE left mouse button right mouse button middle mouse button The following example outputs the mouse position as well as the mouse button that was pressed: Sub MouseUp(Event As Object) Dim Msg As String Msg = "Keys: " If Event.Buttons AND com.sun.star.awt.MouseButton.LEFT Then Msg = Msg & "LEFT " End If If Event.Buttons AND com.sun.star.awt.MouseButton.RIGHT Then Msg = Msg & "RIGHT " End If If Event.Buttons AND com.sun.star.awt.MouseButton.MIDDLE Then Msg = Msg & "MIDDLE " End If Msg = Msg & Chr(13) & "Position: " Msg = Msg & Event.X & "/" & Event.Y MsgBox Msg End Sub Note – VBA : The VBA Click and Doubleclick events are not available in OpenOffice.org Basic. Instead use the OpenOffice.org Basic MouseUp event for the click event and imitate the Doubleclick event by changing the application logic. Keyboard Events The following keyboard events are available in OpenOffice.org Basic: Key pressed user presses a key. Key released user releases a key Events Both events relate to logical key actions and not to physical actions. If the user presses several keys to output a single character (for example, to add an accent to a character), then OpenOffice.org Basic only creates one event. Chapter 11 · Dialogs 159
