Tab controls
When Multiline is enabled, the tabs can appear in more than one row if there is not room for all the tabs in a single row. When Multiline is not enabled, a dual arrow control appears to allow the user to scroll to tabs that do not fit.
To enable multiline display of tabs:
Select the Multiline check box on the General page of the control’s Properties view.
The Multiline property takes a boolean value. The following line allows tabs to be arranged in multiple rows when necessary:
tab_1.Multiline = TRUE
