code generator : structure to form gadgets, bind data

Post by eddy »

Here is a little tool to generate form gadgets based on structure code
- generate load/save structure data
- convert structure field to label text (if label attribute isn't defined) : MyStructureField => "My Structure Field"
- supported decorator attributes : hidden, nolabel, label, mask, min, max
- supported layout attributes : x, y, w, h, lw, dy

Code: Select all
