自定义 Firemonkey 样式 - 控件和样式之间的链接属性?

Custom Firemonkey style - linking properties between control and style?

Delphi XE-6

我正在尝试为 TGroupBox 控件创建自己的样式。

我看了很多演示和教程,但似乎无法理解这一点。

如何使控件中的文本变为空白并显示在样式的文本控件上?

我知道这与样式名称有关,但我不知道我做错了什么。

有人可以提供一个简单的例子吗? 例如,一个 TGroupbox - 在顶部有一个标题,但是如果你想把它放在从顶部向下的横幅上怎么办。创建横幅我可以做,但是我如何才能 link 横幅上带有控件标题 属性 的文本项?

谢谢

您不必自己进行链接。

FireMonkey 控件自己完成:

function TPresentedTextControl.FindTextObject: TFmxObject;
begin
  Result := FindStyleResource('text'); // Do not localize
end;

确保样本中的文本控件命名为 text

我做了一个这样的小例子:

object TStyleContainer
  object TLayout
    StyleName = 'grouboxstylebottom'
    Padding.Left = 2.000000000000000000
    Padding.Top = 8.000000000000000000
    Padding.Right = 2.000000000000000000
    Padding.Bottom = 2.000000000000000000
    Position.X = 410.000000000000000000
    Position.Y = 360.000000000000000000
    Size.Width = 120.000000000000000000
    Size.Height = 100.000000000000000000
    Size.PlatformDefault = False
    Visible = False
    TabOrder = 0
    object TStyleObject
      StyleName = 'background'
      Align = Client
      CapMode = Tile
      Locked = True
      SourceLookup = 'Windows 10 Desktopstyle.png'
      Size.Width = 116.000000000000000000
      Size.Height = 90.000000000000000000
      Size.PlatformDefault = False
      WrapMode = Tile
      SourceLink = <
        item
          CapInsets.Left = 2.000000000000000000
          CapInsets.Top = 2.000000000000000000
          CapInsets.Right = 2.000000000000000000
          CapInsets.Bottom = 2.000000000000000000
          SourceRect.Left = 166.000000000000000000
          SourceRect.Top = 83.000000000000000000
          SourceRect.Right = 213.000000000000000000
          SourceRect.Bottom = 130.000000000000000000
        end>
      object TPanel
        StyleName = 'banner'
        Align = Bottom
        Position.Y = 70.000000000000000000
        Size.Width = 116.000000000000000000
        Size.Height = 20.000000000000000000
        Size.PlatformDefault = False
        TabOrder = 0
      end
      object TText
        StyleName = 'text'
        Align = Bottom
        ClipParent = True
        Locked = True
        HitTest = False
        Margins.Left = 1.000000000000000000
        Margins.Top = 2.000000000000000000
        Margins.Right = 1.000000000000000000
        Margins.Bottom = -15.000000000000000000
        Position.X = 1.000000000000000000
        Position.Y = 70.146484375000000000
        Size.Width = 114.000000000000000000
        Size.Height = 14.853515625000000000
        Size.PlatformDefault = False
        Text = 'Groupbox'
        TextSettings.Font.Family = 'Showcard Gothic'
        TextSettings.WordWrap = False
      end
    end
  end
end

所以最终的控制看起来是这样的:

在这种情况下,将您的 GroupBox 的 StyleLookup 设置为 groupboxstylebottom
