[SOLVED] fill parent of widget with tabwidget

Hi!

I know this is a general task and I have seen several questions related this topic but I did not find the answer for my case.
I would like to ask how can I fill the parent widget of my qtabwidget? anything I have tried di not help me.
I saw this example code:
http://codeprogress.com/cpp/libraries/qt/qtChangeTabTextColor.php#.VCa0S44vC-8
but here the author used setFixedSize, but I would like to do with changeable size. (follow its parent)

Here is my code:
(tmMainWindow is just a class inherited from QMainWindow, nothing special)

@
//#include <QCoreApplication>
#include <QApplication>

#include "tmmainwindow.h"
#include <QWidget>
#include <QtWidgets/QTabWidget>
#include <QVBoxLayout>
#include <QtWidgets/QLabel>

int main(int argc, char *argv[])
{
// texts for each tab
QString st[] = {"file & directory", "date & time", "thread & lock",
"network & socket", "serial"};
int size = sizeof(st) / sizeof(st[0]); // size of text array

//QCoreApplication a(argc, argv);
QApplication a(argc, argv);

tmMainWindow* mw = new tmMainWindow(&a);
QWidget*      wc = new QWidget;             // center widget for tab widget
QTabWidget*   tw = new QTabWidget(wc);      // tab widget for tabs
QWidget*       w = new QWidget[size];
QLabel*        l = new QLabel[size];
QVBoxLayout* vbl = new QVBoxLayout[size];

// each tab -> label, layout, widget, tab
for(int i = 0; i < size; ++i)
{
    l[i].setText(st[i]);
    l[i].setAlignment(Qt::AlignCenter);     // works only within Layout
    //l[i].setStyleSheet("QLabel { color: blue; font-size: 22px; }");
    vbl[i].addWidget(&l[i]);
    //w[i].setStyleSheet("QWidget { background-color: green; }");
    w[i].setLayout(&vbl[i]);
    tw->addTab(&w[i], l[i].text());
}

// tab widget
//wt->setStyleSheet("QWidget { background-color: yellow; }");
//tw->setStyleSheet("QTabWidget { background-color: black; font-size: 18px; }");

// main window
mw->resize(800, 600);
mw->setWindowTitle("tab and menu");
//mw->setStyleSheet("tmMainWindow { background-color: dark grey; }");

mw->setCentralWidget(wc);
mw->show();

return a.exec&#40;&#41;;

}

I am glad if someone has a great idea or solution for me. (I would like to learn and know whether my theory is on the wrong way or not)

Have a nice day :)

Hi and welcome to devnet,

It's too much complication

@
QApplication a(argc, argv); // <- first thing to do

QStringList tabNames;
tabNames << "file & directory"
<< "date & time"
<< "thread & lock"
<< "network & socket"
<< "serial";
QTabWidget *tabWidget = new QTabWidget
foreach(const QString& tabName, tabNames) {
QWidget *widget = new QWidget;
QVBoxLayout *layout = new QVBoxLayout(widget);
QLabel *label = new QLabel(tabName);
layout->addWidget(label);

tabWidget->addTab(tabName, widget);
}

tmMainWindow mw;
mw.setCentralWidget(tabWidget);
mw.show();
return app.exec();

Hi!

It works as cool as it can :)
Thanks a lot, you teached me some basic theories for Qt developing.

You're welcome ! :)

Since it's all good now, please update the thread tittle prepending [solved] so other forum users may know a solution has been found :)
