DrawDesignerObjectHandler Delegate

In This Topic

After the user has edited the object, you are asked by List & Label to draw the object. The event DrawDesignerObject is triggered for this purpose. A Graphics object and the rectangle of the object are passed through EventArguments. Now, you can draw in the work area with the known GDI + methods. While doing so, access to the underlying object properties is naturally possible and useful. The sample listing shows the presentation of the graphic file selected above.

Remarks

Due to a minor inconsistency, conversion of the font size should be carried out manually at the time of printing the text using the Graphics.DrawString, if necessary. The .NET framework calculates it internally as 1/10 inch. If millimeter (1/10) has been indicated as the metric unit (property Units), the size should be multiplied manually by 2.54:
