篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了delphi怎么样选择PageControl1的分页相关的知识,希望对你有一定的参考价值。
delphi中比如我在PageControl1中总共有3页分页, 在另一个基面有3个按钮(分别为1 2 3 ),分别对应PageControl1中的TabSheet1,TabSheet2和TabSheet3,怎么样才能实现我按1他就跳出TabSheet1 按2跳出TabSheet2. 而按3就出现TabSheet3呢?现在我是在程序里面点着哪个,运行的时候,不管点123 就弹出原先点过的那个的
参考技术A PageControl1.ActivePageIndex:=1;或者PageControl1.ActivePage直接写在delphi中,在运行时如何让拖动的控件显示在最上方?
比如窗体上有panel1、panel2、panel3三个控件。可以拖动panel1到panel2上,也可以拖动panel2到panel1上。总之,可以让拖动那个控件能够位于其他的控件上方,而不是被别的控件遮住了。
参考技术A 我也最近才实现了这个功能,可以说是MPI窗口!用PageControl控件可以实现,你把窗体的边框设为无边框,打开的时候最大化,每打开一个窗体就在主窗体的PageControl上面新建一个标签页,标签显示窗体的Caption属性,并把窗体的父控件设标签页,再在PageControl的标签双击事件中写入双击可以关闭当前标签页的事件就可以了! 参考技术B (Sender as TPanel).BringToFront; 参考技术C unit Unit1;

procedure FormCreate(Sender: TObject);
end;

RadioButton1.Caption := '置前';
RadioButton2.Caption := '置后';
RadioButton1.Checked := True;
Panel2.OnClick := Panel1Click;
Panel3.OnClick := Panel1Click;
Panel1.ParentBackground := False;
Panel1.Color := clRed;
Panel2.ParentBackground := False;
Panel2.Color := clLime;
Panel3.ParentBackground := False;
Panel3.Color := clBlue;
end;
procedure TForm1.Panel1Click(Sender: TObject);
begin
if RadioButton1.Checked then TPanel(Sender).BringToFront;
if RadioButton2.Checked then TPanel(Sender).SendToBack;
end;
end.

有这样的一个实类!
