EntitiesCreator

[yannick]

Hello,

I need to allow user to add lines and texts in editor. So i would like to use the class EntitiesCreator.
I read sample EditorDemo and i copy codes in my application but when i click in map nothing appear, i don't get start of line.
So i badly use EntitiesCreator but i don't find what is missing.

I join a simple sample, could you say me what is missing.
Other questions, how can i choose color and thickness of the line, rectangle, polyline, etc..

Best regards, yannick

Hello Yannick,

Thank you for the post.

If you need to add entities programmatically, we suggest to use AddEntityDemo. It shows how to create lines, texts and other entities. Also you can see there how to set properties: color, layer, etc.

If you wish to customize the way of entities creating which is used in Editor demo please use this demo and change it. It has many methods which should be implemented.

Kind regards,
Evgeny
