• The Use Painting DB checkbox is used to include data from the open database. After being included, this data can be edited.
• If the Auto-generate Names checkbox is checked, item names are formed automatically based on the IDs entered by user.
• If both squares and spray cans are present in the work area, setting up colorings becomes possible. To do this, you need to drag the spray can you want to use over the square whose color you want to change. After releasing the mouse button, a dialog box pops up where the desired amount of paint has to be specified.
• All constraints of this database schema are checked; in particular, there can’t be a less than zero amount of paint in the spray can, and the red, green, and blue color components applied to a square can’t exceed 255. (Some of the constraints are checked even before the spray can is dragged – that’s why it’s not possible, e. g., to either use empty cans, or try coloring white squares). If the value entered is correct, the amount of the respective color component on the square will be increased, and the amount of paint in the spray can decreased accordingly.
• For any modifications of the visual model, the XML markup in the XML text box is changed to reflect these modifications. And vice versa, on clicking the Use XML button, the visual model will be set up based on the XML markup. The XML markup used here is fully compatible with the format used in the Data modeling service, so that you can transfer it there directly without any changes (for the time being, by copying and pasting it).
