In the LibreOffice BASIC window for a dialogue that you created, leave the dialogue editor by clicking the name tab of the Module that the dialogue is assigned to. The name tab is at the bottom of the window.
Enter the following code for a subroutine called Dialog1Show. In this example, the name of the dialogue that you created is "Dialog1":
oDialog1 = LoadDialog("Standard", "Dialog1")
Without using "LoadDialog" you can call the code as follows:
oDialog1 = CreateUnoDialog( DialogLibraries.Standard.Dialog1 )
When you execute this code, "Dialog1" opens. To close the dialogue, click the close button (x) on its title bar.
