C＃Winform ToolTip启用/禁用

Question

I am trying to give the user an option to disable and enable the tool tips. In my application, I created a menu strip with two options (EnableToolTip/DisableToolTip). Here my code to set the tool Tips (where ttObj is a global object):

private void loadToolTips()
{

    ttObj.AutoPopDelay = 5000;
    ttObj.InitialDelay = 1000;
    ttObj.ReshowDelay = 500;

    ttObj.SetToolTip(this.btnSetRolesType, "A");
    ttObj.SetToolTip(btnCreateUser, "B");
    ttObj.SetToolTip(btnModifyNum, "C");
    ttObj.SetToolTip(btnFindDups, "D");
    ttObj.ShowAlways = false;

}

And this is where I am trying to disable the tooltips

private void enableToolStripMenuItem_Click(object sender, EventArgs e)
{
    enableToolStripMenuItem.Checked = true;
    disableToolStripMenuItem.Checked = false;
}

private void disableToolStripMenuItem_Click(object sender, EventArgs e)
{
    disableToolStripMenuItem.Checked = true;
    enableToolStripMenuItem.Checked = false;
    ttObj.Hide(this); //this doesn't do anything

}

There isn't much on google or stackoverflow. Some help is much appreciated.

To enable/disable the tool tips, use the Active property. Set it False to disable and when you set it back to True , you'll have your tool tips again without having to re-add them.

private void enableToolStripMenuItem_Click(object sender, EventArgs e)
{
    enableToolStripMenuItem.Checked = true;
    disableToolStripMenuItem.Checked = false;

    ttObj.Active = true;
}

private void disableToolStripMenuItem_Click(object sender, EventArgs e)
{
    disableToolStripMenuItem.Checked = true;
    enableToolStripMenuItem.Checked = false;

    ttObj.Active = false;
}

Alternatively, to just wipe them out, use RemoveAll() . You'll have to re-run loadToolTips() to add them back.

private void disableToolStripMenuItem_Click(object sender, EventArgs e)
{
    disableToolStripMenuItem.Checked = true;
    enableToolStripMenuItem.Checked = false;

    ttObj.RemoveAll();   
}
