Custom widget

I'm trying to programm an qt application, and my design is the following. I need a menubar, toolbar, statusbar and the central widget. In the central widget i need to change among some custom widgets. Till now i have not problem. But when i programm my custom widget and try to put in the centralwidget, my customwidget not resize. Now i'm testing with a simple custom widget that contains 3 textboxes:

Code:

---

editor1 = new QTextEdit;
editor2 = new QTextEdit;
editor3 = new QTextEdit;
splitter = new QSplitter (Qt::Horizontal,this);
splitter->addWidget(editor1);
splitter->addWidget(editor2);
splitter->addWidget(editor3);

---

and in the mainwindows i programm something like this:

Code:

---

CreateToolBars();
CreateStatusBar();
 
QWidget *w = new QWidget;
setCentralWidget(w);
 
TextEditor = new WindowsTextEditor();  //--->this is my custom widget
TextEditor->setSizePolicy(QSizePolicy::Ignored, QSizePolicy::Ignored);
QVBoxLayout *vbox = new QVBoxLayout;
vbox->addWidget(TextEditor);
w->setLayout(vbox);

---

This paint the toolbar, menubar, statusbar and in the central widget puts a little box....
I have tryed to give size to my widget, like this:

Code:

---

TextEditor = new WindowsTextEditor(800,800);

---

and in my custom:

Code:

---

this->setGeometry(0,0,width,height);
editor1 = new QTextEdit;
...

---

But do the same, a little textbox....:confused:
Someone knows what's happening?

Thanks

Did you play with setFixedHeight() & setFixedWidth() for your custom widget.

I have just tested this functions and not work, don't do nothing:

Code:

---

w->setFixedHeight(800);
w->setFixedWidth(800);

---

Could you provide a minimal compilable example reproducing the problem?

I have been clean the programm.....

Here you are...

You didn't add the splitter into the widget's layout.

I have just change the code of my custom widget constructor with (I think is that you are telling me):

Code:

---

editor1 = new QTextEdit;
    editor2 = new QTextEdit;
	editor3 = new QTextEdit;
    splitter = new QSplitter (Qt::Horizontal);//--->change
	splitter->addWidget(editor1);
	splitter->addWidget(editor2);
	splitter->addWidget(editor3);
	QVBoxLayout *vbox = new QVBoxLayout;     //new
	vbox->addWidget(splitter);                         //new
	this->setLayout(vbox);                               //new

And the box is bigger but only shows one white box (text editor) and can't do anything in it (can't write....), and the box do not resize when i resize the mainwindow.

For me it seems your class is completely broken.

You should implement it like so:

Code:

---

#include <QtGui>
 
class X : public QSplitter {
public:
  X() : QSplitter(Qt::Horizontal){
    addWidget(new QTextEdit);
    addWidget(new QTextEdit);
    addWidget(new QTextEdit);
  }
 
};
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  X edit;
  edit.show();
  return app.exec();
}
