 |
|
Hello Infralution Group,
Here I face a tooltip problem with tree Icon.
in the tree MainColumn, I have an Icon (set in GetRowData event handler) and text on the right of Icon. I hope to show different tooltip in both Icon and text, is that possible? or can I set tooltip for a whole row?
Thank you in advance! |

VirtualTree only supports by default Tooltips on cells. If you want to have a tooltip on the Row (or Row icon) then you would need to create your own custom RowWidget class (see "Using Widgets" in the help for more detail) then you would override the OnMouseEnter/OnMouseLeave methods to show your tooltip. The Tree provides methods you can use to do this eg:
| Code: | public override void OnMouseEnter(MouseEventArgs e)
{
string toolTipText = GetToolTipText();
if (toolTipText != null)
{
Tree.ShowToolTip(toolTipText);
}
}
public override void OnMouseLeave(EventArgs e)
{
Tree.HideToolTip();
} |
