TextEdit in QDialog not accepting data

[nbkhwjm]

now i been looking at this for two hours, hopefully someone will make me look bad here.

I have a mainwindow that opens a Qdialog called ExtLogWindow, the window opens fine and I'm happy there.

I send logging events to a function in ExtLogWindow that *should* write them to the Textedit window.

extlogwindow.cpp

#include "extlogwindow.h"
#include "ui_extlogwindow.h"
#include <QDebug>
#include <QSettings>
 
 
ExtLogWindow::ExtLogWindow(QWidget *parent) : QDialog(parent)
{
 
	ui.setupUi(this);
// THIS WORKS OK
	ui.logWindowTextEdit->setText(tr("this is text"));
// ABOVE WORKS OK
	qDebug() << "This is logwindow.cpp";
 
}
 
ExtLogWindow::~ExtLogWindow()
{
 
}
 
void ExtLogWindow::updateLogWindow(QString &entry)
{
 
	qDebug() << "Logwindow.cpp Logentry" << entry;
// THESE DO NOT WRITE DATA
	ui.logWindowTextEdit->setText(tr("this is text #2"));
	ui.logWindowTextEdit->append(tr("TTT%1").arg(entry));
// ABOVE DO NOT WORK
 
}

#include "extlogwindow.h"
#include "ui_extlogwindow.h"
#include <QDebug>
#include <QSettings>


ExtLogWindow::ExtLogWindow(QWidget *parent) : QDialog(parent)
{

	ui.setupUi(this);
// THIS WORKS OK
	ui.logWindowTextEdit->setText(tr("this is text"));
// ABOVE WORKS OK
	qDebug() << "This is logwindow.cpp";

}

ExtLogWindow::~ExtLogWindow()
{

}

void ExtLogWindow::updateLogWindow(QString &entry)
{

	qDebug() << "Logwindow.cpp Logentry" << entry;
// THESE DO NOT WRITE DATA
	ui.logWindowTextEdit->setText(tr("this is text #2"));
	ui.logWindowTextEdit->append(tr("TTT%1").arg(entry));
// ABOVE DO NOT WORK

}

extlogwindow.h

#include "extlogwindow.h"
#include "ui_extlogwindow.h"
#include <QDebug>
#include <QSettings>
#include <QTextEdit>
 
 
ExtLogWindow::ExtLogWindow(QWidget *parent) : QDialog(parent)
{
 
	ui.setupUi(this);
// THIS WORKS OK
	ui.logWindowTextEdit->setText(tr("This entry is from the top"));
// ABOVE WORKS OK
	qDebug() << "This is logwindow.cpp";
 
}
 
ExtLogWindow::~ExtLogWindow()
{
 
}
 
void ExtLogWindow::updateLogWindow(QString &entry)
{
 
	qDebug() << "Logwindow.cpp Logentry" << entry;
 
// THIS DOES NOT WRITE DATA
	ui.logWindowTextEdit->append(tr("LOG: %1").arg(entry));
}

#include "extlogwindow.h"
#include "ui_extlogwindow.h"
#include <QDebug>
#include <QSettings>
#include <QTextEdit>


ExtLogWindow::ExtLogWindow(QWidget *parent) : QDialog(parent)
{

	ui.setupUi(this);
// THIS WORKS OK
	ui.logWindowTextEdit->setText(tr("This entry is from the top"));
// ABOVE WORKS OK
	qDebug() << "This is logwindow.cpp";

}

ExtLogWindow::~ExtLogWindow()
{

}

void ExtLogWindow::updateLogWindow(QString &entry)
{

	qDebug() << "Logwindow.cpp Logentry" << entry;

// THIS DOES NOT WRITE DATA
	ui.logWindowTextEdit->append(tr("LOG: %1").arg(entry));
}

The code produces the following on the command line: When I call:
Where "entry" = "test"

ExtLogWindow logger(this);
	logger.updateLogWindow(entry);

ExtLogWindow logger(this);
	logger.updateLogWindow(entry);

To copy to clipboard, switch view to plain text mode 

Command line output

This is logwindow.cpp 
Logwindow.cpp Logentry "This entry is from the top" 
Logwindow.cpp Logentry "test"

This is logwindow.cpp 
Logwindow.cpp Logentry "This entry is from the top" 
Logwindow.cpp Logentry "test"

To copy to clipboard, switch view to plain text mode 

The following shows up in Texedit window

This entry is from the top

This entry is from the top

To copy to clipboard, switch view to plain text mode 

Any ideas? The variable "entry" is seen by the function or i would not get the command line output of "logwindow.cpp logentry "test"" Why does it not populate the data from the other function to QTextEdit?

try to add data like this

...
ui.logWindowTextEdit->textCursor().insertText(entry);
...

...
ui.logWindowTextEdit->textCursor().insertText(entry);
...

Nope

void ExtLogWindow::updateLogWindow(QString &entry)
{
	qDebug() << "Logwindow.cpp Logentry" << entry;
// THESE DO NOT WRITE DATA
	ui.logWindowTextEdit->textCursor().insertText(entry);
	ui.logWindowTextEdit->setText(tr("Inside the function\n"));
	ui.logWindowTextEdit->append(tr("From the other class %1\n").arg(entry));
// ABOVE DO NOT WORK
 
}

void ExtLogWindow::updateLogWindow(QString &entry)
{
	qDebug() << "Logwindow.cpp Logentry" << entry;
// THESE DO NOT WRITE DATA
	ui.logWindowTextEdit->textCursor().insertText(entry);
	ui.logWindowTextEdit->setText(tr("Inside the function\n"));
	ui.logWindowTextEdit->append(tr("From the other class %1\n").arg(entry));
// ABOVE DO NOT WORK

}

nbkhwjm,

I created an example based on what you described below in what you are doing and I couldn't replicate the problem your experiencing. So I'm going to pass on the example I was working with so you can compare and see if maybe something sticks out at you that could be the problem child.

The example has a Mainwindow with log entry area, and you can access the textdialog (logger) for viewing from View menu. Hopefully it is close to what you are dealing with to find the problem.
