After the user has used the tool TOOL_REGION to select an area, I would like it so that the area remains selected, but the user cannot drag the floater to another area. In other words, I would like the selected region to be displayed (with the crawling ants outline) but not actually be a floater... Any suggestions?

Hello,
What is the exact LEADTOOLS version that you use? And what is the programming interface (COM, .Net, API, etc.)?
Can you please provide me with a code snippet that shows how exactly the user can select a region on the image?
Anyway, if the user selects a regular region on the image, he shouldn't be able to move it unless the region converted to floater.
Thanks,
Maen Badwan

14.0 of the C++ class library.
The code used when switching to the region tool is:
//I have tried setting this value to TRUE and FALSEm_LBitmapWnd.SetAutoFloaterToRgn(FALSE);
m_LBitmapWnd.SetToolType(TOOL_REGION);
m_LBitmapWnd.SetRegionType(REGION_TYPE_RECT);
m_LBitmapWnd.SetAutoRgnToFloater(FALSE);
After the region is drawn, it becomes a floater and can be moved.

Hello,
The help topic "Floaters and Regions in the LBitmapWindow Class" in the LEADTOOLS ClassLib C++ help file discusses this as follows:
+-----+
m_BitmapWindow.SetAutoFloaterToRgn(TRUE)
m_BitmapWindow.SetToolType(TOOL_REGION)
m_BitmapWindow.SetRegionType(REGION_TYPE_RECT)
Click and drag mouse to create floater
m_BitmapWindow.CancelRgn() //this removes the floater, but leaves the bitmap region
+-----+
In this scenario, a region is created and the floater is destroyed.
Thanks,

Yes, we can no longer drag the selected area at that point, but the crawling dots outline also disappears. I would like to be able to see that area is selected (like a floter), without it being movable.

Hello,
The LEADTOOLS C++ Class library Barcode demo shows how to draw a region (by the mouse) with no need to draw a floater.
You can find the Barcode demo installed on the following path on your machine:
...\Program Files\LEAD Technologies, Inc\LEADTOOLS 14.5\Examples\CLASSLIB\MSVC5\Barcode
When you open the demo, you will find the code under the "View"\"Select a Region" menu.
Thanks,
Maen Badwan
