Draw text

This draw text sample application demonstrates the splined text rendering capabilities of ArcObjects. The user clicks on the map to track a line, and the MapControl method DrawText is used to place the text within the TextBox along the tracked line. Note that at least two clicks are required for the line and text to appear on the MapControl.

 

The application uses the AddShapeFile method to load in the continents sample data which is then symbolized. The OnClick event uses either the TrackRectangle method to zoom in if the right or middle mouse button has been used, or adds the new point to the line and updates the display through the refresh method. The refresh method is used to draw the esriViewForeground, thereby removing any previously drawn annotation, and triggering the MapControl's OnAfterDraw event. The OnAfterDraw event uses the DrawShape and DrawText methods to draw the line and text onto the MapControl in response to the refresh of the esriViewForeground phase.
