设置TabPage的标题颜色 [英] Set TabPage Header Color
问题描述
问候,
我有一个标签控件,我想有标签1有它的文本颜色变化上的事件。
我发现像 C#的答案 - TabPage的颜色事件
和<一个href=\"http://stackoverflow.com/questions/1849801/c-winform-how-to-set-the-base-color-of-a-tabcontrol-not-the-tabpage\">C# Winform的:如何设置一个TabControl的基本颜色(不是Tab页)
但使用这些组的所有颜色,而不是一个。
所以我希望有一种方法用标签来实现这一点,我想更改为方法,而不是一个事件?
是这样的:
公共无效SetTabPageHeaderColor(TabPage的页面,色色)
{
//文本这里
}
如果您想要的颜色的标签,请尝试以下code:
this.tabControl1.DrawMode = TabDrawMode.OwnerDrawFixed;
this.tabControl1.DrawItem + =新System.Windows.Forms.DrawItemEventHandler(this.tabControl1_DrawItem);私人字典&LT; TabPage的,颜色和GT; TabColors =新词典&LT; TabPage的,颜色和GT;();
私人无效SetTabHeader(TabPage的页面,色色)
{
TabColors [页码] =颜色;
tabControl1.Invalidate();
}
私人无效tabControl1_DrawItem(对象发件人,DrawItemEventArgs E)
{
//e.DrawBackground();
使用(刷BR =新SolidBrush(TabColors [tabControl1.TabPages [e.Index]]))
{
e.Graphics.FillRectangle(BR,e.Bounds);
SZ的SizeF = e.Graphics.MeasureString(tabControl1.TabPages [e.Index]。文本,e.Font);
e.Graphics.DrawString(tabControl1.TabPages [e.Index]。文本,e.Font,Brushes.Black,e.Bounds.Left +(e.Bounds.Width - sz.Width)/ 2,e.Bounds.Top +(e.Bounds.Height - sz.Height)/ 2 + 1); 矩形RECT = e.Bounds;
rect.Offset(0,1);
rect.Inflate(0,-1);
e.Graphics.DrawRectangle(Pens.DarkGray,RECT);
e.DrawFocusRectangle();
}
}
Greetings,
I have a tab control and I want to have 1 of the tabs have it's text color changed on a event. I've found answers like C# - TabPage Color event and C# Winform: How to set the Base Color of a TabControl (not the tabpage) but using these sets all colors instead of one.
So I was hoping there is a way to implement this with the tab I wish to change as a method instead of a event?
Something like:
public void SetTabPageHeaderColor(TabPage page, Color color)
{
//Text Here
}
If you want to color the tabs, try the following code:
this.tabControl1.DrawMode = TabDrawMode.OwnerDrawFixed;
this.tabControl1.DrawItem += new System.Windows.Forms.DrawItemEventHandler(this.tabControl1_DrawItem);
private Dictionary<TabPage, Color> TabColors = new Dictionary<TabPage, Color>();
private void SetTabHeader(TabPage page, Color color)
{
TabColors[page] = color;
tabControl1.Invalidate();
}
private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
{
//e.DrawBackground();
using (Brush br = new SolidBrush (TabColors[tabControl1.TabPages[e.Index]]))
{
e.Graphics.FillRectangle(br, e.Bounds);
SizeF sz = e.Graphics.MeasureString(tabControl1.TabPages[e.Index].Text, e.Font);
e.Graphics.DrawString(tabControl1.TabPages[e.Index].Text, e.Font, Brushes.Black, e.Bounds.Left + (e.Bounds.Width - sz.Width) / 2, e.Bounds.Top + (e.Bounds.Height - sz.Height) / 2 + 1);
Rectangle rect = e.Bounds;
rect.Offset(0, 1);
rect.Inflate(0, -1);
e.Graphics.DrawRectangle(Pens.DarkGray, rect);
e.DrawFocusRectangle();
}
}
