History
GitHub repo has the history.txt file which lists all major changes.
Requirements
- Lazarus: 1.8+.
- Tested on: Windows, Linux GTK2/Qt, macOS.
How to use it like TPageControl
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?
- Add tabs OnChange event handler.
- In this event handler: a) hide all frames, b) show frame, which is assigned to current TabIndex.
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.
var
d: TATTabData;
begin
d:= t.GetTabData(t.TabIndex);
if Assigned(d) then
(d.TabObject as TMyFrame).Show;
end;
License

ATTabs is merged into ATFlatControls repo: https://github.com/Alexey-T/ATFlatControls/ . Some wiki documentation is in the "wiki" subfolder of that repo.
