Using ToolButton repeatedly in MapInfo 19

[Evgeny Kleiman]

I have a ToolButton with a handler:

Dim tlbMyPolyline as This

tlbMyPolyline = MICtrlCollAddStrStrInt(groupControlColl, "tlbMyPolyline", "Draw new segment", ControlType_ToolButton)

...

'Handler 

Call SetRbnToolBtnCtrlCallingHandler(tlbMyPolyline, "MyPolyline")

'****************************

Here MyPolyline is a subroutine. It contains, particularly, an instruction

   Run Menu Command M_TOOLS_POLYLINE

This allows to draw a polyline and then the sub processes the result.

The button and handler work fine at first time. But if to try to draw a new line without to click the button once more the handler does not work. I have to note that the same code

works in MapInfo 15 without additional clicks. Could the problem be solved?

Thank you.

Your sub procedure shouldn’t call the standard polygon tool. Instead you should use CommandInfo to get to the object drawn with your custom tool button.

You are also required to insert this object into the table.

In your example, the user is switched from using your custom tool to using the standard polyline tool when you use  Run Menu Command M_TOOLS_POLYLINE
