Hi,
I am using the customized type provider as the typeprovider in the RuleSetDialog, now I want to display some description for the type when user edit the ruleset, so I add some summary ahead of the class. But the summary doesn't display when
I edit the condition/then action. Can anyone tell me is it possible to display the tips for the type, any help will be appreciated.
Here is my code.
/// <summary>
/// Material tip
/// </summary>
[Serializable]
public static class M
{
/// <summary>
/// Product tip
/// </summary>
public static class Product
{
}
}
And the "Material tip" does not show when I edit the condition.

Hello guys,
I have fixed this problem now, I listed the solution below in case someone want to implement the same functionility.
Add MouseHover, MouseLeave, MouseLeave events to the textbox, when the mouse stayed on the text for 300mm, pop up the tooltips.
Demo code looks like this.
class TestTextBox : TextBox
{
System.Timers.Timer timer;
int cout = 0;
Point pt = new Point();
ToolTip tooltip;
string splitString;
protected override void OnCreateControl()
{
base.OnCreateControl();
timer = new System.Timers.Timer();
timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
timer.Interval = 100;
timer.Enabled = false;
splitString = ".() |&^!\0\n\r\"'=[]+-*/\\";
tooltip = new ToolTip();
}
protected override void OnMouseHover(EventArgs e)
{
base.OnMouseHover(e);
timer.Enabled = true;
}
protected override void OnMouseLeave(EventArgs e)
{
base.OnMouseLeave(e);
timer.Enabled = false;
}
protected override void OnMouseMove(MouseEventArgs e)
{
base.OnMouseMove(e);
if (!timer.Enabled)
timer.Enabled = true;
cout = 0;
pt.X = e.Location.X;
pt.Y = e.Location.Y;
}
void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
if (cout >= 300)
{
timer.Enabled = false;
ShowToolTip();
}
else
cout += 100;
}
void ShowToolTip()
{
this.Invoke(new MethodInvoker(delegate
{
int index = this.GetCharIndexFromPosition(pt);
char c = this.GetCharFromPosition(pt);
if (splitString.Contains(c.ToString()))
{
return;
}
int endIndex = 0;
for (int i = index + 1; i < this.Text.Length; i++)
{
if (splitString.Contains(this.Text[i].ToString()))
{
endIndex = i;
break;
}
}
if (endIndex == 0)
{
endIndex = this.Text.Length;
}
int startIndex = 0;
for (int i = index - 1; i >= 0; i--)
{
if (splitString.Contains(this.Text[i].ToString()))
{
startIndex = i + 1;
break;
}
}
string key = this.Text.Substring(startIndex, endIndex - startIndex);
if (!string.IsNullOrEmpty(key))
{
Point point = this.GetPositionFromCharIndex(startIndex);
point.Y += (int)Math.Ceiling(this.Font.GetHeight()) + 2;
point.X += 2;
tooltip.Show(key, this, point, 2000);
}
}));
}
}
Heere is the effect:
