我正在为一个menustrip着色以匹配我的应用主题。但是,每次尝试时,我都会在面板分隔符左侧看到这种奇怪的视觉异常(白色矩形)。还有一些奇怪的复选框定位(可能相关?)。
造成这种情况的原因是什么,如何将其删除?
谢谢
示例代码:
private Color MainColor = Color.FromArgb(39, 40, 34);
public class MenuStripRenderer : ToolStripProfessionalRenderer
{
protected override void OnRenderMenuItemBackground(ToolStripItemRenderEventArgs e)
{
Rectangle rect = new Rectangle(Point.Empty, e.Item.Size);
if (e.Item.Selected)
{
Color color = Color.FromArgb(24, 25, 19);
using (SolidBrush brush = new SolidBrush(color))
e.Graphics.FillRectangle(brush, rect);
}
else
{
using (SolidBrush brush = new SolidBrush(MainColor))
e.Graphics.FillRectangle(brush, rect);
}
}
protected override void OnRenderItemText(ToolStripItemTextRenderEventArgs e)
{
e.Item.ForeColor = Color.White;
base.OnRenderItemText(e);
}
protected override void OnRenderSeparator(ToolStripSeparatorRenderEventArgs e)
{
base.OnRenderSeparator(e);
}
public MenuStripRenderer() : base(new MenuStripColors()) { }
}
public class MenuStripColors : ProfessionalColorTable
{
public override Color ToolStripDropDownBackground
{
get { return MainColor; }
}
public override Color ToolStripContentPanelGradientBegin
{
get { return MainColor; }
}
public override Color ToolStripContentPanelGradientEnd
{
get { return MainColor; }
}
public override Color MenuItemSelected
{
get { return MainColor; }
}
public override Color MenuItemBorder
{
get { return MainColor; }
}
public override Color MenuItemSelectedGradientBegin
{
get { return MainColor; }
}
public override Color MenuItemSelectedGradientEnd
{
get { return MainColor; }
}
public override Color MenuBorder
{
get { return MainColor; }
}
}
// In the forms Load()
this.menuStrip1.Renderer = new MenuStripRenderer();
this.menuStrip1.BackColor = MainColor;
this.menuStrip1.ForeColor = Color.White;
答案 0 :(得分:2)
我相信你也必须覆盖ImageMargin绘图:
protected override void OnRenderImageMargin(ToolStripRenderEventArgs e) {
//base.OnRenderImageMargin(e);
using (SolidBrush brush = new SolidBrush(MainColor)) {
e.Graphics.FillRectangle(brush, e.AffectedBounds);
}
}
我不知道是什么导致了您的复选标记问题,因为我无法在我的计算机上复制该问题。我猜也许这是你窗户上的图形DPI设置。
