| 14 | + | ## History | |
| 15 | + | ||
| 16 | + | GitHub repo has the [history.txt file](https://github.com/Alexey-T/ATFlatControls/blob/master/history.txt) which lists all major changes. | |
| 17 | + | ||
| 18 | + | ## Requirements | |
| 19 | + | ||
| 20 | + | - Lazarus: 1.8+. | |
| 21 | + | - Tested on: Windows, Linux GTK2/Qt, macOS. | |
| 22 | + | ||
| 23 | + | ## How to use it like TPageControl | |
| 24 | + | ||
| 25 | + | 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 | + | ||
| 27 | + | - Add tabs OnChange event handler. | |
| 28 | + | - In this event handler: a) hide all frames, b) show frame, which is assigned to current TabIndex. | |
| 29 | + | ||
| 30 | + | 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 | + | ||
| 32 | + | ``` Pascal | |
| 33 | + | var | |
| 34 | + | d: TATTabData; | |
| 35 | + | begin | |
| 36 | + | d:= t.GetTabData(t.TabIndex); | |
| 37 | + | if Assigned(d) then | |
| 38 | + | (d.TabObject as TMyFrame).Show; | |
| 39 | + | end; | |
| 40 | + | ``` | |
