Resize of widget's array

mimamrafi

Hi everyone, I'm sorry about this newbie's question. I want to resize the widget's array, this is my latest codes

//maingui.h
#include "channelframe.h"
...
private:
    Ui::MainGUI *ui;
    ChannelFrame *CF[8];

//maingui.cpp
MainGUI::MainGUI(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainGUI)
{
    ui->setupUi(this);

    ui->tabWidget->widget(0)->setLayout(new QVBoxLayout);
    CF.resize (9);
    const uint array_size = sizeof(CF)/sizeof(CF[0]);
    for (uint i = 0; i < array_size; i++)
    {
        CF[i] = new ChannelFrame;
        connect(CF[i], &ChannelFrame::Next, this, &MainGUI::NextFocus);
        CF[i]->Channel(i);
        ui->tabWidget->widget(0)->layout()->addWidget(CF[i]);
    }
}

I know it can't work. I can't use the function CF.resize() How can I resize the size of the widget's array? Are there any clues? Thank you

@mimamrafi You can't resize an array. Use QVector instead.

Now it's work, Thanks. This is my latest code

//maingui.h
#include "channelframe.h"
...
private:
    Ui::MainGUI *ui;
   QVector<ChannelFrame*> CF;

//maingui.cpp
MainGUI::MainGUI(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainGUI)
{
    ui->setupUi(this);

    ui->tabWidget->widget(0)->setLayout(new QVBoxLayout);
    CF.resize(8);
    for (int i = 0; i < CF.size(); i++)
    {
        CF[i] = new ChannelFrame;
        connect(CF[i], &ChannelFrame::Next, this, &MainGUI::NextFocus);
        CF[i]->Channel(i);
        ui->tabWidget->widget(0)->layout()->addWidget(CF[i]);
    }
}
