delphi - 带 TAction 的 TSpeedButton - 自动生成的禁用图像仅考虑黑色

转载作者：行者123 更新时间：2023-12-03 14:54:57

首先，我已经知道，当你实现一个TSpeedButton时，当你分配它的Glyph时，如果你没有多个字形，那么NumGlyphs 应为 1，禁用时为 it will automatically use the same image自动生成字形的禁用版本。

但是，在我的情况下，我正在为此速度按钮分配一个操作。 TActionManager 的 Images 和 DisabledImages 都指向同一个 TImageList。我还测试了根本没有分配任何 DisabledImages 的情况，以及使用全黑蒙版创建图像的副本，并通过 DisabledImages 分配该副本。

启用后，字形显示得很好(基于操作上设置的图像)。但当它被禁用时，仅图像中的纯黑色将用于禁用图像。任何具有除纯黑色之外的任何颜色的颜色，甚至稍微偏黑的颜色，都将被完全忽略，并且在渲染禁用图像时不包括在内。

这是测试启用的图像和自动生成的禁用图像之间的比较。该图像只是带有一些垂直线的 16x16 位图。从最右边开始，有一条全黑的线，然后是左边稍浅的线。

如您所见，禁用时，它只考虑全黑线。下一条线仅比全黑稍浅。

我无法自己分配Glyph 属性，因为它会被分配给它的操作覆盖。我也无法在图像列表上设置两个字形宽的图像，因为这些图像广泛用于许多其他没有多个字形概念的地方。我也不想为我的图像使用全黑。

如何让禁用的 TSpeedButton(由于禁用 TAction 的结果)在分配有操作时显示禁用(灰显)图像？

注意:TBitBtn 或任何依赖于 Glyph 的控件也会发生同样的情况。

为了举例，这是我使用的测试位图:

<小时/>

事实上，在Vcl.Buttons单元中，在函数TButtonGlyph.CreateButtonGlyph中，以下代码似乎明确只考虑黑色区域:

{ Create a disabled version }
with MonoBmp do
begin
  Assign(FOriginal);
  HandleType := bmDDB;
  Canvas.Brush.Color := clBlack;
  Width := IWidth;
  if Monochrome then
  begin
    Canvas.Font.Color := clWhite;
    Monochrome := False;
    Canvas.Brush.Color := clWhite;
  end;
  Monochrome := True;
end;
with TmpImage.Canvas do
begin
  Brush.Color := clBtnFace;
  FillRect(IRect);
  Brush.Color := clBtnHighlight;
  SetTextColor(Handle, clBlack);
  SetBkColor(Handle, clWhite);
  BitBlt(Handle, 1, 1, IWidth, IHeight,
    MonoBmp.Canvas.Handle, 0, 0, ROP_DSPDxax);
  Brush.Color := clBtnShadow;
  SetTextColor(Handle, clBlack);
  SetBkColor(Handle, clWhite);
  BitBlt(Handle, 0, 0, IWidth, IHeight,
    MonoBmp.Canvas.Handle, 0, 0, ROP_DSPDxax);
end;

最佳答案

将速度按钮放在组框上并禁用组框，您不需要禁用字形，但仍然只有 1 个图像图像将在那里，但按钮仍然明显被禁用
