Hello,

One more question...

I'm working with the designer, then copy and past the code as Fudadmin pointed out. It seems easy. Now I have many labels. They are all passive and show some text. I would like to declare just one label widget like this:

Label label;

and the use 'label' everywhere (I used to do so with another GUI in C). So I believed that the following code:

	label.SetLabel(t_("Label 1"));
	label.SetAlign(ALIGN_CENTER);
	label.LeftPosZ(236, 48);
	label.TopPosZ(96, 19);
	Add(label);

	label.SetLabel(t_("Label 2"));
	label.SetAlign(ALIGN_CENTER);
	label.LeftPosZ(136, 48);
	label.TopPosZ(46, 49);
	Add(label);

could show two labels. Instead seems that 'Label 2' override the first one. So at the end I see only 1, the last.
This means that I have to use two separate variables (object):

Label label, label1;
	label.SetLabel(t_("Label 1"));
	label.SetAlign(ALIGN_CENTER);
	label.LeftPosZ(236, 48);
	label.TopPosZ(96, 19);
	Add(label);

	label1.SetLabel(t_("Label 2"));
	label1.SetAlign(ALIGN_CENTER);
	label1.LeftPosZ(136, 48);
	label1.TopPosZ(46, 49);
	Add(label1);

and both appear. I would like to know if there is some trick to use the same object or I must in any case declare each object I use.

Thank you
Luigi

Label is a class (dead description, recipe, mold, pattern set of genes, etc.).
label1, label2 etc. are class instances (real live objects like someone's children).

By declareing:
Label label1, label2;
you instanciate them or make the very begining of life.

Then you shape them.
label1 - red hair, big ears...
label2 - yellow hair, small head...
etc...

Can you imagine the same child beeing a daughter and a son, having all green and red hair at the same time? Smile

...Unless you put some genes (methods) to do so at diferent times and positions.

E.g make a loop and make to display the same label with different params every 100ms. But this, I think, would create blinking and waste of computer power.
So maybe it's better to create a different label for different positions? Smile

Edit:
P.S. Btw, you can use an array of labels... and calculate their positions in a loop... Smile
