how to create column headers by selecting radiobuttons and checkboxes

[pkjag]

Hi all
So i was wondering how one would go about setting the column fields of a table by selecting a radio button or checkbox.

something like:
selecting checkme

QCheckBox *checkmeCheckBox = new QCheckBox(this, tr("checkme"));

QCheckBox *checkmeCheckBox = new QCheckBox(this, tr("checkme"));

To copy to clipboard, switch view to plain text mode 

will create a column header with the same name checkme so that my table will have new columns with the same names as the radiobuttons and checkboxes i set checked

thanks in advance.

Hi , I wrote some codes
opened a project which it's base class is QMainWindow

added to .h

private slots:
    void addColumn();
    void deleteColumn();

private slots:
    void addColumn();
    void deleteColumn();

To copy to clipboard, switch view to plain text mode 

added to mainwindow.cpp

connect(ui->chkBox_add,SIGNAL(clicked()),this,SLOT(addColumn()));
connect(ui->chkBox_delete,SIGNAL(clicked()),this,SLOT(deleteColumn()));

connect(ui->chkBox_add,SIGNAL(clicked()),this,SLOT(addColumn()));
connect(ui->chkBox_delete,SIGNAL(clicked()),this,SLOT(deleteColumn()));

To copy to clipboard, switch view to plain text mode 

void MainWindow::addColumn()
{
    ui->chkBox_add->setChecked(false);
    ui->tableWidget->setColumnCount(ui->tableWidget->columnCount()+1);
}
 
void MainWindow::deleteColumn()
{
    ui->chkBox_delete->setChecked(false);
    ui->tableWidget->setColumnCount(ui->tableWidget->columnCount()-1);
}

void MainWindow::addColumn()
{
    ui->chkBox_add->setChecked(false);
    ui->tableWidget->setColumnCount(ui->tableWidget->columnCount()+1);
}

void MainWindow::deleteColumn()
{
    ui->chkBox_delete->setChecked(false);
    ui->tableWidget->setColumnCount(ui->tableWidget->columnCount()-1);
}

Hi and thanks for your reply
So why did you setChecked(false)?
Say you have the checkboxes in a wizard and after the wizard setup wraps up it stores the checkboxes' history and uses that to create the.columns, what would you change in your code to integrate that?
Also since your checkbox name is chkBox_add, what should be done so that my column has the same name?

[studentQt]

sorry , I couldn't understand what u want to say exactly

I try to reply as far as I understand

I create the chkBox_add and chkBox_delete chechBoxes in .ui file

then I'll try to make same name the new adding columns

if I find a way , I write here

the .ui file display below

-------------------------------
setChecked(false) , that's just my choice , I thought it's more good with that feature

-------------------------------

u can make same name the column in this way

QTableWidgetItem *item = new QTableWidgetItem(QString(""),QTableWidgetItem::Type);  
// or QTableWidgetItem *item = new QTableWidgetItem(" ",QTableWidgetItem::Type);
ui->tableWidget->setHorizontalHeaderItem(column, item); // don't forget the column array starts from 0

QTableWidgetItem *item = new QTableWidgetItem(QString(""),QTableWidgetItem::Type);  
// or QTableWidgetItem *item = new QTableWidgetItem(" ",QTableWidgetItem::Type);
ui->tableWidget->setHorizontalHeaderItem(column, item); // don't forget the column array starts from 0

To copy to clipboard, switch view to plain text mode 

for example if u define the item in that way u copy the names

QTableWidgetItem *item = new QTableWidgetItem(ui->tablewidget->horizontalHeaderItem(column-1)->text(),QTableWidgetItem::Type);
ui->tableWidget->setHorizontalHeaderItem(column, item);

QTableWidgetItem *item = new QTableWidgetItem(ui->tablewidget->horizontalHeaderItem(column-1)->text(),QTableWidgetItem::Type);
ui->tableWidget->setHorizontalHeaderItem(column, item);

What i'm trying to say is. I have a wizard that i created separately and also a mainwindow that's supposed to launch a table once you click finish in the wizard. So in the wizard i have a couple of checkboxes and radiobuttons, when i click them so that they stay checked i want that to generate the columns of my table in mainwindow with the same names as the checkboxed and radiobuttons i set checked?
Is it possible to use your code for that?

[studentQt]

I wrote somes , hope it's your answer what u want

and it works good , I'll add them end of the reply

But the place I don't understand is how u can see a cople of checkboxes and radiobuttons to create a project which is base class is QMainWindow in the wizard

pls can u take screen shots or take a video

I wrote all of them because of I don't understand your checkbox and radiobutton event exactly

[pkjag]

So this is part of my wizard:

skool.jpg

and i want all the checked checkboxes and radiobuttons to appear as columns with the same names as the checkboxes in my mainwindow which is launched after i click the finish button in the last page of the wizard.
This is the last page of the wizard:

New Picture1.jpg

And this is the mainwindow where the table is supposed to run once i click finish in the last page:

New Picture.jpg

hope you can help??

[studentQt]

Probably , u want a thing like that way

u'll click to a button then the program'll check the all checkboxes

-------------------------
there is a thing u should now : radiobuttons are different from checkboxes
After u click a radiobutton , if u click another radiobutton , checking feature of the radiobutton which it's first chechked goes unchecked

-------------------------

I'll add a video about that thing what I uderstand

[pkjag]

Yeah i know enough about radio buttons and checkboxes, so is there anyway you can help?

[studentQt]

I wrote a program about checkboxes

[pkjag]

Could you post the code snippets here cause i cannot play the video at this moment cause i have some problems with the video plugins in my browser??

[studentQt]

this is mainwindow.cpp content

#include "mainwindow.h"
#include "ui_mainwindow.h"
 
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}
 
MainWindow::~MainWindow()
{
    delete ui;
}
 
void MainWindow::on_pushButton_clicked()
{
    QString name = ui->checkBox->text();
    ui->checkBox->setChecked(true);
    if(ui->checkBox_2->text() == name) ui->checkBox_2->setChecked(true);
    if(ui->checkBox_3->text() == name) ui->checkBox_3->setChecked(true);
}

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)

}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::on_pushButton_clicked()
{
    QString name = ui->checkBox->text();
    ui->checkBox->setChecked(true);
    if(ui->checkBox_2->text() == name) ui->checkBox_2->setChecked(true);
    if(ui->checkBox_3->text() == name) ui->checkBox_3->setChecked(true);
}

other files are same (mainwindow.h,main.cpp and .pro files)

[pkjag]

But how does that relate to creating columns with the same name as the checkboxes??

[studentQt]

sorry , I'll try on it

[wysota]

What's exactly the issue here? It seems to me the problem is trivial -- iterate over marked checkboxes and add columns to a table with names corresponding to checkboxes.

[studentQt]

sorry , did I do a mistake?

[studentQt]

that's not about this issue
I'm very surprised when I see that
