I want to check Mouse In/Out on Tab Area of TabPage in C# Winform.
There are Event MouseLeave, MouseEnter, MouseMove, but there work for whole TabPage. I just want for Tab only.
TabControl tabControl = new TabControl();
TabPage tabpage = new TabPage();
tabpage.MouseMove += new System.Windows.Forms.MouseEventHandler(panel1_MouseMove);
tabControl.Controls.Add(tabpage);
this.Controls.Add(tabControl);
I'm thinking that If I get to know the Tab area so that I can write Code in MouseMove event for the same, Is there any better way to do the same.
I want for the area pointed by the arrow in the attached image.
The GetTabRect function would help you here:
TabPage mouseTab = null;
void tabControl1_MouseMove(object sender, MouseEventArgs e) {
TabPage checkTab = null;
for (int i = 0; i < tabControl1.TabPages.Count; ++i) {
if (tabControl1.GetTabRect(i).Contains(e.Location)) {
checkTab = tabControl1.TabPages[i];
break; // To avoid unnecessary loop
}
}
if (checkTab == null && mouseTab != null) {
mouseTab = null;
} else if (checkTab != null) {
if (mouseTab == null || !checkTab.Equals(mouseTab)) {
mouseTab = checkTab;
// or do something here...
}
}
}
And to handle the mouse leaving the tab header area:
void tabControl1_MouseLeave(object sender, EventArgs e) {
if (mouseTab != null) {
// do something here with mouseTab...
mouseTab = null;
}
}
您可以在“选项卡”的整个区域上放置一个面板控件,然后将您提到的事件用于该面板控件。
