如何使用Mdi容器

发布于 2024-11-16 16:48:08 字数 366 浏览 2 评论 0原文

当我想从 ToolStripMenu 打开新表单时，我通常会这样做

private void alumnoToolStripMenuItem_Click(object sender, EventArgs e)
    {
        frmAlumno x = new frmAlumno();
        x.ShowDialog();
    }

，但老师告诉我这是错误的，因为这不应该发生..

所以我想我必须使用 MdiContainer 但我现在不知道如何编写代码...请一些帮助...

原文

This is what I usually do when I want to open a new form from a ToolStripMenu

private void alumnoToolStripMenuItem_Click(object sender, EventArgs e)
    {
        frmAlumno x = new frmAlumno();
        x.ShowDialog();
    }

but a teacher told me that it´s wrong because this shouldn´t happen..

So I guess I have to use MdiContainer but I´m not sure of how to write the code now... Please some help...

如果您使用MDI，您应该调用Show，而不是ShowDialog。您还需要设置MdiParent。

Form2 newMDIChild = new Form2();

// Set the Parent Form of the Child window.
newMDIChild.MdiParent = this;

// Display the new form.
newMDIChild.Show();

如何：创建 MDI 子表单

If you use MDI, you should call Show, not ShowDialog. Also you need to set MdiParent.

Form2 newMDIChild = new Form2();

// Set the Parent Form of the Child window.
newMDIChild.MdiParent = this;

// Display the new form.
newMDIChild.Show();

我将回答您实际问题的解决方案，而不是描述如何使用 MdiContainer，因为您实际上并不需要它。 :)

表单有一个 ShowInTaskbar 属性，默认为 true。将其设置为false，表单将不再出现在任务栏中。

private void alumnoToolStripMenuItem_Click(object sender, EventArgs e)
{
    frmAlumno x = new frmAlumno();
    x.ShowInTaskbar = false;
    x.ShowDialog();
}

有关详细信息，请参阅 MSDN。

I'm going to answer with a solution to your actual problem instead of describing how to use MdiContainer, since you don't actually need it. :)

Forms have a ShowInTaskbar property that defaults to true. Set it to false and the form will no longer appear in the task bar.

private void alumnoToolStripMenuItem_Click(object sender, EventArgs e)
{
    frmAlumno x = new frmAlumno();
    x.ShowInTaskbar = false;
    x.ShowDialog();
}

See MSDN for more information.
