Customizing the Tab control
The Tab control has settings for controlling the position and
appearance of the tabs. Each tab can have its own label, picture, and
background color.
All tabs share the same font settings, which you set on the Tab
control’s Font property page.
Pop-up menus and property sheets for Tab
controls and tab pages
A Tab control has several elements, each with its own pop-up menu
and property sheet. To open the property sheet, double-click or select
Properties on the pop-up menu.
Where you click determines what element you access.

same if all the tab labels are short, but if you have a mix of long and
short labels, justified labels can be different sizes unless Fixed Width
is on.
This figure illustrates the effect of combining some of these
settings. Tab Position is Top:
This sample Tab control is set up like an address book. It has tabs

If you are working in the User Object painter on an object you will
use as a tab page, you can make the same settings on the TabPage page of
the user object’s property sheet that you can make in the tab page’s
property sheet.
This example has a picture and text assigned to each tab page. Each
tab has a different background color. The Show Picture and Show Text
settings are both on:

you can set in a script, allowing you to change the appearance of the Tab
control dynamically during execution.
