Home How to automatically save the GUI to file? (Paradigm)
 The good (and bad) old Delphi taught us the "classic" way of building application because of the way we write code "behind" the IDE. Based on this paradigm, I built some time ago a library that allows me to save/load the GUI to INI file with a single line of code. LoadForm(FormName)  BAM! That's it! No more INI files! The library only saves "relevant" properties. For example, for a TCheckBox it saves only its Checked property not also its Color or Top/Left. But it is more than enough. Saving the form has no issues. However, I have "problems" during app initialization. They are not quite problems, but the initialization code is not that nice/elegant. For example when I assign Checkbox1.Checked := True it will trigger the OnClick event (supposing that the checkbox was unchecked at design time). But assigning a False value (naturally) will not trigger the OnClick event. Therefore, I have to manually call CheckBox1Click(Sender) after SaveForm(FormName) to make sure that whatever code is in CheckBox1Click, it gets initialized. But this raises another problem. The CheckBox1Click(Sender) might be called twice during application start up (once by SaveForm and once my me, manually). Of course, in theory the logic of the program should be put in individual objects and separated from the GUI. But even if we do this, the initialization problem remains. You load the properties of the object from disk and you assign them to the GUI. When you set whatever value you have in your object to Checkbox1, it will (or not) call CheckBox1Click(Sender) which will set the value back into the object. On app startup: procedure TForm.FormCreate (Sender: TObject); begin LogicObject.Load(File); // load app logic Checkbox1.Checked := LogicObject.Checked; // assign object to GUI end; procedure TForm.CheckBox1Click(Sender: TObject); begin LogicObject.Checked := Checkbox1.Checked; end;  Probably the solution involves writing stuff like this for EVERY control on the form: OldEvent := CheckBox1.OnClick; CheckBox1.OnClick := Nil; CheckBox1.Checked := something; CheckBox1.OnClick := OldEvent;  Not elegant. Question: How do you solve this specific problem OR what is your approach when saving/restoring your GUI to/from disk?
