我该如何去改变tabcontrol(ownerdrawfixed/flatbutton外观)的完整背景颜色?不只是顶部,而是整个背景?我正在使用C#WinForms。更改选项卡控件的背景颜色
Font fntTab;
Brush bshBack;
Brush bshFore;
if (e.Index == this.tabControl1.SelectedIndex)
{
fntTab = new Font(e.Font, FontStyle.Bold);
bshBack = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, SystemColors.ScrollBar, SystemColors.ScrollBar, System.Drawing.Drawing2D.LinearGradientMode.BackwardDiagonal);
bshFore = Brushes.Black;
//bshBack = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, Color.LightSkyBlue , Color.LightGreen, System.Drawing.Drawing2D.LinearGradientMode.BackwardDiagonal);
//bshFore = Brushes.Blue;
}
else
{
fntTab = e.Font;
bshBack = new SolidBrush(Color.Red);
bshFore = new SolidBrush(Color.Aqua);
//bshBack = new SolidBrush(Color.White);
//bshFore = new SolidBrush(Color.Black);
}
string tabName = this.tabControl1.TabPages[e.Index].Text;
StringFormat sftTab = new StringFormat();
e.Graphics.FillRectangle(bshBack, e.Bounds);
Rectangle recTab = e.Bounds;
recTab = new Rectangle(recTab.X, recTab.Y + 4, recTab.Width, recTab.Height - 4);
e.Graphics.DrawString(tabName, fntTab, bshFore, recTab, sftTab);
使用WPF也许是...不,认真,看到这个:https://www.codeproject.com/Articles/91387/Painting-Your-Own-Tabs-Second-Edition – z3nth10n
