1. Complex interfaces should be more or less evenly distributed among classes and their constructors. That's why classes exists!
2. I personally know 3 main ways of creating widgets:
2.1 As Mirek mentioned here - with Layout Designer
2.2 Program everything yourself by hand
2.3 Copy code from *.lay files and create your own programmed classes.
Which case you would like to discuss?
|
The package AddressBook shows how to integrate the product of the Layout Designer with the code. Unfortunately I saw strange signs like <...> ,  , that I do not understand yet... So points 2.1 and 2.3 cannot be discussed with me, at least not in the immediate future.
Fortunatly remains another possibility, 2.2. It should be the most general approach although at the cost to write more code lines... but I'm ready.
The current problem is to put between the menubar and the status bar a group of 4 tab pages. Each of them will contain other widgets. I've inquired the available documentation and the code example to get useful advices but both AddressBook and theIde packages use layout files. So I do not know how to let appear some thing that could resemble a tabbed window. Nevertheless I tried many weird things like that below good to open a window but without tabs.
Any advices for a minimalist approach as the example below? After that something will appear I will try to merge it with the menu and status bar and then start to fill each tab.
Thank you,
Luigi

did you mean this?:
#include <CtrlLib/CtrlLib.h>
GUI_APP_MAIN
{
TopWindow w;
TabCtrl tabs;
w.Add(tabs.SizePos()); //fills all available space...
tabs.Add("one");
tabs.Add("two");
tabs.Add("three");
//add more accordingly or create in a a loop...
w.Run();

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

Well, each label has to have its own variable (in U++, those variables are actual GUI elements, not just some info that is placed to dialog definition).
However, you can do this:
Array<Label> label;
....
labels.Add();
label.Top().SetLabel(t_("Label 1"));
label.Top().SetAlign(ALIGN_CENTER);
label.Top().LeftPosZ(236, 48);
label.Top().TopPosZ(96, 19);
Add(label.Top());
labels.Add();
label.Top().SetLabel(t_("Label 2"));
label.Top().SetAlign(ALIGN_CENTER);
label.Top().LeftPosZ(136, 48);
label.Top().TopPosZ(46, 49);
Add(label.Top());

Or, yes, like this. But in this case some strange symbols <..> come to help and instantiation of children(daughters-labels) is achieved by labels.Add() - each label is then created "inside".

Yes, I agree it's not confortable for the child... and maybe for the parents too  .
Here is my new achievement. I used your method of copy and past from designer after CTRL+T. About Designer I will report later in the appropriate place of the forum. Below is the code I have modified being all the rest of the program remained the same.
//personalized tab (1 child) widget
class LuigiTab : public ParentCtrl {
Button btnAdd, btnDel, btnClear, btnModify;
DocEdit doc;
LabelBox lbox;
Label label[10];

~LuigiTab(){;}
};
LuigiTab::LuigiTab() {

Add(lbox);
label[0].SetLabel(t_("Name")).SetAlign(ALIGN_CENTER).LeftPosZ(28, 132).TopPosZ(32, 19);
Add(label[0]);

arr.AddColumn("ID FIDE");

arr.AddColumn("ID Nat");
arr.AddColumn("Rat Nat");
arr.AddColumn("K");
arr.AddColumn("Available");
At the moment this class is instancied in each tab while I want it stays only in tab 1. I believe I must realize a different class for each tab like:
class LuigiTab1 : public ParentCtrl // tab 1
class LuigiTab2 : public ParentCtrl // tab 2
class LuigiTab3 : public ParentCtrl // tab 3
and then create an instance for each of them.
I need to add data to the drop list button. Unfortunatly I have no example in the documentation and I do not know how to do.
In the coloumn available of the arrayctrl I would like to have a chekbox (checked means available, and unchecked unavailable). Any suggestion?
In the addressbook package there is an example similar to what I want to do: simply fill the fields and then push the data in then arrayctrl. This is my next task.
The geometry of the whole tab is not perfect but now it is important to learn how to dispatch the data between the object and how to retrieve them. The beauty can wait.
Thank you,
Luigi

, I'm very impressed.
