QDialog crashing problem (Header)

[boro_11]

I have a problem with following code...

#ifndef SIGNALSETTINGS_H
#define SIGNALSETTINGS_H
 
#include <QDialog>
#include "signalfile.h"
#include <QLabel>
#include <QLineEdit>
#include <QCheckBox>
 
struct SignalProperties{
    int signalHeight;
    int verticalPosition;
    int slotNumber;
    bool isVisible;
    QColor bgColour;
    QColor signalColour;
    QColor fillColour;
    int signalThicness;
    bool showAsAnalog;
    Signal *signal; //Pointer to signal
};
 
 
class SignalSettings : public QDialog
{
    Q_OBJECT
 
public:
    explicit SignalSettings(SignalProperties *p, QWidget *parent = 0);
    void paintEvent(QPaintEvent *event);
    ~SignalSettings();
 
 
 
private:
    SignalProperties *properties;
 
    QLabel *labelFGColour;
    QLabel *labelBGColour;
    QLineEdit *inputHeight;
 
    int krneki; // <------ Problem, works great without this line but but program crashes with this line of code.
 
 
signals:
    void signalPropertiesChanged();
 
public slots:
    void onBGButtonClicked();
    void onFGButtonClicked();
    void onShowHide(int state);
    void onSignalHeightChange();
};
 
#endif // SIGNALSETTINGS_H

#ifndef SIGNALSETTINGS_H
#define SIGNALSETTINGS_H

#include <QDialog>
#include "signalfile.h"
#include <QLabel>
#include <QLineEdit>
#include <QCheckBox>

struct SignalProperties{
    int signalHeight;
    int verticalPosition;
    int slotNumber;
    bool isVisible;
    QColor bgColour;
    QColor signalColour;
    QColor fillColour;
    int signalThicness;
    bool showAsAnalog;
    Signal *signal; //Pointer to signal
};


class SignalSettings : public QDialog
{
    Q_OBJECT

public:
    explicit SignalSettings(SignalProperties *p, QWidget *parent = 0);
    void paintEvent(QPaintEvent *event);
    ~SignalSettings();



private:
    SignalProperties *properties;

    QLabel *labelFGColour;
    QLabel *labelBGColour;
    QLineEdit *inputHeight;

    int krneki; // <------ Problem, works great without this line but but program crashes with this line of code.


signals:
    void signalPropertiesChanged();

public slots:
    void onBGButtonClicked();
    void onFGButtonClicked();
    void onShowHide(int state);
    void onSignalHeightChange();
};

#endif // SIGNALSETTINGS_H

I have a custom QDialog widget, and it worked great. Now I want to save some integer and if I write the int in header, program sometimes (not always) crashes when QDialog (SignalSettings) should open...

Any ideas why it works without that line and why not when I include it in my code?

This is my first post so I say Hi to you all

Added after 13 minutes:

Amm ok above code actualy works ok, but if I put integer between pointers as below, than it crashes quiet often.

this code crashes:

private:
    SignalProperties *properties;
    int krneki;                                   //<---- if integer between pointers than code irregulary crashes
    QLabel *labelFGColour;
    QLabel *labelBGColour;
    QLineEdit *inputHeight;

private:
    SignalProperties *properties;
    int krneki;                                   //<---- if integer between pointers than code irregulary crashes
    QLabel *labelFGColour;
    QLabel *labelBGColour;
    QLineEdit *inputHeight;

You need to have a problem elsewhere.

What is the stacktrace at the time of the crash?

Sorry for late reply,

If I run it in DEBUGING mode, it never stops with error. No matter how many times I open that dialog, I get error the second or third time if I compile in release mode and I never get an error if I compile with debug mode...

What would be the difference between those two modes?

I will trie to compile on linux box to see if there is any difference there.
