How to change cursor for ToolStripButton?

Question

I want to change the user cursor when it hovers over a specific ToolStripButton, but not at other ToolStrip elements. How to set the button cursor?

Answer 1

Because ToolStripItem does not inherit Control, it does not have a Cursor property.

You can set the form cursor to the MouseEnter event and restore the form cursor in the MouseLeave event, the following VB example:

Dim savedCursor As Windows.Forms.Cursor

Private Sub ToolStripButton1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles ToolStripButton1.MouseEnter
    If savedCursor Is Nothing Then
        savedCursor = Me.Cursor
        Me.Cursor = Cursors.UpArrow
    End If
End Sub

Private Sub ToolStripButton1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles ToolStripButton1.MouseLeave
    Me.Cursor = savedCursor
    savedCursor = Nothing
End Sub

Update

And here is the same answer in C #:

private Cursor savedCursor;

private void ToolStripButton1_MouseEnter(object sender, EventArgs e) {
    if (savedCursor == null) {
        savedCursor = this.Cursor;
        this.Cursor = Cursors.UpArrow;
    }
}

private void ToolStripButton1_MouseLeave(object sender, EventArgs e) {
    this.Cursor = savedCursor;
    savedCursor = null;
}

Answer 2

To change the cursor, you must set the Toolstrip.Cursor property. Yes, you are right, this will change the mouse cursor for all buttons on the toolbar.

Go down to Win32 and process WM_SETCURSOR. You can put your own logic to change the cursor based on testing the strokes for the button. Check out this article by Raymond Chen for a better understanding of how the Cursor is set.
