Chaning border color from QTextTable with QColor-Dialog

? Offline

Hi. How can i Change the Color of QTextTable border with a Color Dialog? I know that i can Change it with QBrush and QTextTableFormat but how can i do this with a Color Dialog?

Hi,

If you want to pick a color from a Color Dialog, just use the static method getColor in <QColorDialog>

QColor color = QColorDialog::getColor();

Then you can use this color to change your QTextTAbleFormat.

see you!

Hi Henrik,

as you requested by chat this is a more deep example.

#ifndef MAINWIDGET_H
#define MAINWIDGET_H

#include <QWidget>

class QResizeEvent;
class QTextTable;

class MainWidget : public QWidget
{
    Q_OBJECT

public:
    MainWidget(QWidget *parent = 0);
    ~MainWidget();

protected:
    void resizeEvent(QResizeEvent *event) override;

public slots:
    void contextMenuRequested(const QPoint& pos);
    void showColorPicker();

private:
    QTextTable *_table;
};

#endif // MAINWIDGET_H

#include "MainWidget.h"
#include <QTextEdit>
#include <QTextCursor>
#include <QTextTable>
#include <QMenu>
#include <QAction>
#include <QColorDialog>

#include <QDebug>

MainWidget::MainWidget(QWidget *parent)
    : QWidget(parent)
{
    setContextMenuPolicy(Qt::CustomContextMenu);
    connect(this, &QWidget::customContextMenuRequested,this, &MainWidget::contextMenuRequested);
}

MainWidget::~MainWidget()
{

}

void MainWidget::contextMenuRequested(const QPoint& pos)
{
    qDebug() << "Menu Requested";
    QMenu *contextMenu = new QMenu(this);


    QAction *action = contextMenu->addAction("Color");

    contextMenu->popup(mapToGlobal(pos));

    connect(action, &QAction::triggered, this, &MainWidget::showColorPicker);
}

void MainWidget::resizeEvent(QResizeEvent *event)
{
    QTextEdit *te = new QTextEdit(this);
    QTextCursor cursor = te->textCursor();

    QTextTableFormat tf;
    tf.setBorderBrush(Qt::red);
    _table = cursor.insertTable(5, 5, tf);
}

void MainWidget::showColorPicker()
{
    QColor color = QColorDialog::getColor();

    QTextTableFormat tf = _table->format();
    tf.setBorderBrush(color);
    _table->setFormat(tf);
}

Maybe you could change the QTextDocument style, to change all the tables in the document, this is somenthing I don't know.

Hope this helps!
