Dismiss ToolTip Window?

[jp2paint]

Is there a way to make the tool tip window go away once the Comb Box has been opened?

 

 

 

A reusable method like sketched out below could handle each Combo Box's DropDown and DropDownClosed event:

    private ComboBox ComboBox1, ComboBox2, ComboBox3;
    private const String CBO1_TOOLTIP = "Shape type\nClick to open list\nShortcut keys: A (next shape), Shift+A (previous shape)";
    private const String CBO2_TOOLTIP = "Text for ComboBox2";
    private const String CBO3_TOOLTIP = "Text for ComboBox3";

    private void InitializeComponent_Example()
    {
        // ComboBox1:
        ComboBox1.DropDown += new EventHandler(DropDown_Dropping);
        ComboBox1.DropDownClosed += new EventHandler(DropDown_Close);
        ComboBox1.Tag = CBO1_TOOLTIP;
        toolTip1.SetToolTip(ComboBox1, CBO1_TOOLTIP);
        // ComboBox2:
        ComboBox2.DropDown += new EventHandler(DropDown_Dropping);
        ComboBox2.DropDownClosed += new EventHandler(DropDown_Close);
        ComboBox2.Tag = CBO2_TOOLTIP;
        toolTip1.SetToolTip(ComboBox2, CBO2_TOOLTIP);
        // ComboBox3:
        ComboBox3.DropDown += new EventHandler(DropDown_Dropping);
        ComboBox3.DropDownClosed += new EventHandler(DropDown_Close);
        ComboBox3.Tag = CBO3_TOOLTIP;
        toolTip1.SetToolTip(ComboBox3, CBO3_TOOLTIP);
    }

    private void DropDown_Close(object sender, EventArgs e)
    {
        var ctrl = sender as ComboBox;
        if (ctrl != null)
        {
            toolTip1.SetToolTip(ctrl, String.Format("{0}", ctrl.Tag));
        }
    }

    private void DropDown_Dropping(object sender, EventArgs e)
    {
        var ctrl = sender as ComboBox;
        if (ctrl != null)
        {
            toolTip1.SetToolTip(ctrl, null);
        }
    }

If this is worth doing, my hope is that providing the code is helpful.

 

I don't know if this is still a .NET project or what language it is currently in.

You could just move your mouse off the button. The tooltip goes away almost immediately.
