Text Color on Model/View s

[JediSpam]

I am working through model/view programming and cannot figure out how to modify text color of "111, 222, 333" from the following example. Should I be looking at the QStandardItemModel documentation or QList? Thanks!



// modelview.cpp
#include <QTreeView>
#include <QStandardItemModel>
#include <QStandardItem>
#include "mainwindow.h"

const int ROWS = 2;
const int COLUMNS = 3;

MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
treeView = new QTreeView(this);
setCentralWidget(treeView);
standardModel = new QStandardItemModel ;

QList<QStandardItem *> preparedRow =prepareRow("first", "second", "third");
QStandardItem *item = standardModel->invisibleRootItem();
// adding a row to the invisible root item produces a root element
item->appendRow(preparedRow);

QList<QStandardItem *> secondRow =prepareRow("111", "222", "333");
// adding a row to an item starts a subtree
preparedRow.first()->appendRow(secondRow);

treeView->setModel(standardModel);
treeView->expandAll();
}

QList<QStandardItem *> MainWindow::prepareRow(const QString &first,
const QString &second,
const QString &third)
{
QList<QStandardItem *> rowItems;
rowItems << new QStandardItem(first);
rowItems << new QStandardItem(second);
rowItems << new QStandardItem(third);
return rowItems;
}

void QStandardItem::setForeground ( const QBrush & brush )

Sets the brush used to display the item's foreground (e.g. text) to the given brush.


Did you try it?

I'm adding


item->setForeGround(Qt::red); //NEW
item->appendRow(preparedRow);


and no go? It builds but colors don't change.

Nope.


rowItems << new QStandardItem(first);
rowItems << new QStandardItem(second);
rowItems << new QStandardItem(third);

Try to set foreground for a particular item containing text.

You need to set it on the items you are currently creating anonymously in prepareRow(). Items are individually coloured, it is not inherited from sibling or parent items.

You may also be able to change the entire table colouring using a style sheet.

Thanks guys I figured it out!

how man... thank you for not just said you find it, but also show your code resolved the problem.... the other one are really happy you share (good thinking... very great).
each time i read someone has same problem than me and share the solution like you... i'm very happy. In my mind, i tell me that this guys not just think about himself.
;)

so, for me, by follow the idea, i do a:

QStandardItem *a = new QStandardItem("new one");
a->setForeground(QBrush(Qt::red, Qt::SolidPattern));

(that is the view of the solution i share with you) :)
so this works just fine.
