单击选项卡控件的选定选项卡页眉时如何触发事件 [英] How to trigger event when clicking on a selected tab page header of a tab control

问题描述

我正在用 C# 做一个 Winform 应用程序，我有一些标签页，比如 tabPage1、tabPage2 和 tabPage3，在一个标签控件中，并且 tabPage1 被选中.

I am doing a Winform application in C# and I have some tab pages, say tabPage1, tabPage2 and tabPage3, in a tab control, and tabPage1 is selected.

我想在点击任何标签页标题时触发事件，但我只能为页面更改执行此操作(通过使用SelectedIndexChanged) 但不要点击选定的标签页标题.

I want to trigger event when any tab page header is clicked, but I could do it only for page change (by using SelectedIndexChanged) but not click on a selected tab page header.

我尝试了 Selecting 和 Selected 事件，但它们都不起作用.我在 MSDN 上搜索，但没有找到在页眉上定义的任何 Click 事件.那么我应该如何实现这一目标?

I tried with Selecting and Selected events but both of them didn't not work. I searched on MSDN but didn't find any Click event defined on a page header. So how should I achieve this?

另一个问题，是否有可能以及如何检测选定标签页上的DoubleClick?

One further question, is it possible, and how, to detect DoubleClick on a selected tab page?

推荐答案

只需使用 tabcontrol 的 MouseDoubleClick 事件.您必须迭代选项卡以找出单击的特定选项卡:

Just use the tabcontrol's MouseDoubleClick event. You'll have to iterate the tabs to find out what specific tab was clicked:

    private void tabControl1_MouseDoubleClick(object sender, MouseEventArgs e) {
        for (int ix = 0; ix < tabControl1.TabCount; ++ix) {
            if (tabControl1.GetTabRect(ix).Contains(e.Location)) {
                // Found it, do something
                //...
                break;
            }
        }
    }

请记住，这对用户来说是完全无法发现的，他永远不会想到双击该选项卡.你必须写一本手册.

Do keep in mind that this is completely undiscoverable to the user, he'll never think to double-click the tab. You'll have to write a manual.
