How to set tooltip text for annotations

In 13, we could set tooltip text for viewer control. But in 15 (using with c#) there is no way to set tooltip text for viewer(rasterimageviewer) or annotations.

How can we do this using c#.

Thanks,
Suresh

Hello,

If you mean that you want to set ToolTip text for Annotation toolbar buttons, you can do this by using the AnnAutomationObject.ToolBarToolTipText property.
This property gets or sets the text that appears as a ToolTip for this AnnAutomationObject toolbar button.

For more information, please read the following topics in the LEADTOOLS .Net documentation:
- ToolBarToolTipText Property 
- Annotation Toolbar.
- AnnAutomationManager Class

If you mean something else, please let me know.

Hi Maen,

I want to be able to set tooltip for annotation objects (for ex: rectangles). When a user moves mouse on to a rectangle (or other object), i want to show the tool tip (let's say the rectangle's width). How can we do this?

Hi - is this feature available in version 17 of Leadtools?

I want to check this issue on my side, so please provide me with the following information:
1. Are you using LEADTOOLS v17.0 or v17.5?
2. What is the programming language (C#, VB.NET, etc.) that you use?
3. What is the build number (file version info) of Leadtools.dll that you use?
4. What is the Visual Studio version (2005, 2008, 2010, 2012, 2013, etc.) that you use?
5. What is the Target Framework (2.0, 3.0, 3.5, 4.0, etc.) of your application?
6. Provide me with more details about what exactly you are looking to accomplish.

I am attaching a small VB.NET 2010 LEADTOOLS NET 3.5 v17.0 project that shows how you can show a tooltip when the user hover the cursor over the annotation object.

Instructions to use the project:
===============
1. Open the project using VS 2010.
2. Make sure the path of the image is correct in the code.
3. Run the project.
4. Click the Load button to load the default image.
5. Select the annotation object that you want to draw from the toolbar (Annotation Rectangle for example).
6. Draw the object on the image.
7. Check the "Perform Hit Testing" check box.
8. Move the mouse cursor to the borders of the Rectangle object.
9. A tooltip should appear that contains the type of the annotations object (this applies for all types of annotations objects).
===============

Thanks, that gets me pointed in the right direction.  Users may find it confusing to toggle manually between Design and Run modes to see the tool tip.  You can eliminate the need to toggle modes by removing the condition "AndAlso checkHitTest.Checked" in the _viewer_MouseMove procedure.  However, when you remove that condition resizing and rotating get a little quirky.  I will keep experimenting.

In your last reply, you mentioned the following:
"However, when you remove that condition resizing and rotating get a little quirky".

Can you provide me with more details about this problem?

The annotations flicker quite a bit during edit.  If you resize an annotation then let go of the mouse button without moving the mouse the annotation does not change sizes until you move the mouse.  Its a little difficult to explain.  I would recommend you made the code change I described and try it yourself.

I think the problem appears because the tooltip steals the focus from the annotation object while resizing. I fixed this issue in the code by force hiding the tooltip while resizing the annotation object. I am attaching the modified demo.

This looks very promising.  I am going to experiment with it some more.  Thanks!
