Properties Model.Name (String) control element name You can specify the title that appears in the title bar of a dialog with the following model property: Model.Title (String) dialog title (only applies to dialogs) Position and Size You can query the size and position of a control element using the following properties of the model object: Model.Height (long) height of control element (in ma units) Model.Width (long) width of control element (in ma units) Model.PositionX (long) X-position of control element, measured from the left inner edge of the dialog (in ma units) Model.PositionY (long) Y-position of control element, measured from top inner edge of the dialog (in ma units) To ensure platform independence for the appearance of dialogs, OpenOffice.org uses the Map AppFont (ma) internal unit to specify the position and size within dialogs. An ma unit is defined as being one eighth of the average height of a character from the system font defined in the operating system and one quarter of its width. By using ma units, OpenOffice.org ensures that a dialog looks the same on different systems under different system settings. If you want to change the size or position of control elements for runtime, determine the total size of the dialog and adjust the values for the control elements to the corresponding part ratios. Note – The Map AppFont (ma) replaces the Twips unit to achieve better platform independence. Focus and Tabulator Sequence You can navigate through the control elements in any dialog by pressing the Tab key. The following properties are available in this context in the control elements model: Model.Enabled (Boolean) activates the control element Model.Tabstop (Boolean) allows the control element to be reached through the Tab key Model.TabIndex (Long) position of control element in the order of activation Finally, the control element provides a getFocus method that ensures that the underlying control element receives the focus: getFocus control element receives the focus (only for dialogs) 154 OpenOffice.org 3.2 BASIC Guide · March 2010
Multi-Page Dialogs Properties A dialog in OpenOffice.org can have more than one tab page. The Step property of a dialog defines the current tab page of the dialog whereas the Step property for a control element specifies the tab page where the control element is to be displayed. The Step-value of 0 is a special case. If you set this value to zero in a dialog, all of the control elements are visible regardless of their Step value. Similarly, if you set this value to zero for a control element, the element is displayed on all of the tab pages in a dialog. Designing Page 1 of the dialog In the preceding example, you can also assign the Step value of 0 to the dividing line as well as the Cancel, Prev, Next, and Done buttons to display these elements on all pages. You can also assign the elements to an individual tab page (for example page 1). The following program code shows how the Step value in event handlers of the Next and Prev buttons can be increased or reduced and changes the status of the buttons. Sub cmdNext_Initiated Dim cmdNext As Object Dim cmdPrev As Object cmdPrev = Dlg.getControl("cmdPrev") cmdNext = Dlg.getControl("cmdNext") cmdPrev.Model.Enabled = Not cmdPrev.Model.Enabled cmdNext.Model.Enabled = False Dlg.Model.Step = Dlg.Model.Step + 1 End Sub Sub cmdPrev_Initiated Dim cmdNext As Object Dim cmdPrev As Object cmdPrev = Dlg.getControl("cmdPrev") cmdNext = Dlg.getControl("cmdNext") cmdPrev.Model.Enabled = False cmdNext.Model.Enabled = True Dlg.Model.Step = Dlg.Model.Step - 1 End Sub A global Dlg variable that references an open dialog must be included to make this example possible. The dialog then changes its appearance as follows: Chapter 11 · Dialogs 155
