| 23 | 20 | ## How to use it like TPageControl | |
| 24 | 21 | ||
| 25 | 22 | Make some new panel, which will be like TPageControl. Place ATTabs on it, make Align=alTop. Now you create several Forms or Frames onto this panel (they have Parent:=Panel1; Align:=alClient;). How to switch these frames on changing tabs? | |
| 26 | 23 | ||
| 27 | 24 | - Add tabs OnChange event handler. | |
| 28 | 25 | - In this event handler: a) hide all frames, b) show frame, which is assigned to current TabIndex. | |
| 29 | 26 | ||
| 30 | 27 | When you create a new tab, you can set its TabObject property. Set TabObject to a frame. When OnChange is called, get TabIndex, call GetTabData() for this index, and read TabObject for this tab. Show the frame, which is stored in this TabObject, hide all others. | |
| 31 | 28 | ||
| 32 | 29 | ``` Pascal | |
| 33 | 30 | var | |
| 34 | 31 | d: TATTabData; | |
| 35 | 32 | begin | |
| 36 | 33 | d:= t.GetTabData(t.TabIndex); | |
| 37 | 34 | if Assigned(d) then | |
| 38 | 35 | (d.TabObject as TMyFrame).Show; | |
| 39 | 36 | end; | |
| 40 | 37 | ``` | |
