How do I update the expansion tooltip size after calling NSTextField setStringValue:?

阅读更多关于 How do I update the expansion tooltip size after calling NSTextField setStringValue:?

When a view contains an NSTextField with the expansion tooltip enabled and the text doesn't fit, then the user hovers the cursor over the field, OS X shows an expansion tooltip. If you then call setStringValue: to change the text content of the NSTextField , the expansion tooltip's size is not updated. For instance, if the original text was 100 characters long but the new text is only 50 characters long, hovering over the new text will show an expansion tooltip large enough for 100 characters containing the new text. This is true even if the new string fits entirely in the NSTextField , which

Tipsy won't recognize d3 elements in asp.net

阅读更多关于 Tipsy won't recognize d3 elements in asp.net

问题 I need to change the background color of the tool tip which will show on mouse over on a hyperlink (for using in firefox and ie6 & higher).

Show series value over any point on chart using tooltip c#

阅读更多关于 Show series value over any point on chart using tooltip c#

So I've seen lots of examples on using tooltip to show chart data when hovering over a data point, but I was hoping to show the values when my mouse is simply over the chart and not necessarily over a particular data point (i.e. the whitespace everywhere else). I would also eventually like to have a small circle or square on the data point itself but that can come later. Can anyone tell me how to do this? I will include my current code below. private void chData_MouseMove(object sender, MouseEventArgs e) { HitTestResult pos = chData.HitTest(e.X, e.Y); if (pos.ChartElementType ==
