Default Object Templates
There is a set of default object templates in the DO\Bin folder ("M_" is for metric):
Barcode.xml
Container.xml
Group.xml
Image.xml
LabelField.xml
Line.xml
Pane.xml
Rectangle.xml
Table.xml
TextField.xml
TextLabel.xml
M_Barcode.xml
M_Container.xml
M_Group.xml
M_Image.xml
M_LabelField.xml
M_Line.xml
M_Pane.xml
M_Rectangle.xml
M_Table.xml
M_TextField.xml
M_TextLabel.xml
To customize the properties of each of these objects, you can copy these templates into the User\Overrides folder and modify for your needs.
Some templates don't have the full set of attributes defined in the template, e.g. for TextField.xml it specifies <border visible="no"/> but does not define border thickness. If you want to adjust the thickness of the border you can copy the border definition from another template or from a form you design. To see an object's XML in Design, select the object and type Alt+Ctrl+N.
