Hi @SGaist,
About starting with black color, it is just because my application provides a color gradient functionality. By default it is between white and black. But user will be able to change the two extrem colors. So, if he/she decides to change the final color, default initial color is black, just in case he/she clicks on OK without doing anything else.

I am experiencing this problem on 5.11.2 running Linux Mint. So it is still there.

Using the following formulation:
QColorDialog dlg(colored->getColor());
dlg.setOption(QColorDialog::DontUseNativeDialog);
dlg.setOption(QColorDialog::ShowAlphaChannel);
dlg.open(this,SLOT(slot_colorChanged(QColor)));
dlg.exec();

First problem: the dialog initializes with color black, not the given color. When pressing OK, the slot is triggered
but the color is always color white, whatever is selected in the dialg. So essentially it does not work at all.

using the formulation
QColor newColor = QColorDialog::getColor(m_color, this, QString(), QColorDialog::DontUseNativeDialog);
does work as was mentioned before

@Qt-Enthusiast
Nope.
Fast way is to make new button or menu
that clear the color on the selected item.

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!

Hi,

You should add what backend you are using, Qt version etc.

Such as ColorDialog, how to switch the language of the dialog that are available in the Qt is as follows .
Page that was in reference

#include <QApplication> #include <QTranslator> #include <QLibraryInfo> int main(int argc, char *argv[]) { //1 : Get the language setting of the system QTranslator qtTranslator; qtTranslator.load("qt_" + QLocale::system().name(), QLibraryInfo::location(QLibraryInfo::TranslationsPath)); QApplication a(argc, argv); //2 : Installation of language setting a.installTranslator(&qtTranslator); return a.exec(); }

Hi and welcome to devnet,

What Linux distribution are you using ?
