How to include .txt on Qt

mrjj

Maybe you use it above where you define it or maybe u didnt show it how CostInfo is defined.

Payx

I defined my QMap here :

QMap<QRgb, CostInfo > Costs = {
	{ QColor(255 , 0 , 0 ).rgb(), { "://fraise.png", 10 }},
	{ QColor(0 , 255 , 0 ).rgb(), { "://balleverte.png", 20 }},
	{ QColor(0 , 0 , 255 ).rgb(), { "://ballebleue.png", 20 }},
	{ QColor(255 , 255 , 255 ).rgb(), { "://balleblanche.png", 20 }},
	{ QColor(255 , 128 , 0 ).rgb(), { "://ballepeche.png", 20 }},
	{ QColor(0 , 0 , 0 ).rgb(), { "://noir.png", 20 }},
	{ QColor(102 , 51 , 0 ).rgb(), { "://marron.png", 20 }},
	{ QColor(255 , 102 , 78 ).rgb(), { "://rose.png", 20 }},
	{ QColor(0 , 204 , 204 ).rgb(), { "://turquoise.png", 20 }},
	{ QColor(255 , 178 , 102 ).rgb(), { "://beige.png", 20 }},
	{ QColor(76 , 0 , 153 ).rgb(), { "://violet.png", 20 }},
	{ QColor(100 , 100 , 100 ).rgb(), { "://gris.png", 20 }},
};

And this is a function call no ?

QMapIterator<QRgb, CostInfo>i;

mrjj

Hi
And where is the definition for CostInfo ?

Payx

i do not know, i thought CostInfo is the cost near the picture so i didnt needed to defined it no ?

Flotisable

@Payx
the compiler only knows the fundamental types or types defined.
so you need to define CostInfo or compiler will give you an error.

Payx

@Flotisable Thank you,

so i have to define CostInfo as an int ?

Flotisable

@Payx
in your case, one of the value you give is { "://fraise.png", 10 }, which is composed of a string and a integer

it seems CostInfo should look like this

struct CostInfo
{
  QString imageName;
  int     cost;
};

Payx

Okay understood how it works now.

Why it say that "Costs" is not declared, it is the name of the QMap right ?

mrjj

@Payx
Yes Costs is the QMap variable.

Payx

How do i declare a QMap ?

i tried

QMap<QRgb, CostInfo > Costs;

mrjj

@Payx
Yes that is how you declare an empty QMap called Costs.

Payx

Yes but it say that CostInfo is not declared again

mrjj

@Payx
CostInfo must be declared before you use it in QMap
Where is it?
you used to have struct CostInfo declaration.

Payx

I put my declaration of CostInfo in my .h

mrjj

@Payx
and is that .h file included in the same file where u have the Qmap def ?

Payx

i got

QMap<QRgb, CostInfo > Costs = {
	{ QColor(255 , 0 , 0 ).rgb(), { "://fraise.png", 10 }},
	{ QColor(0 , 255 , 0 ).rgb(), { "://balleverte.png", 20 }},
	{ QColor(0 , 0 , 255 ).rgb(), { "://ballebleue.png", 20 }},
	{ QColor(255 , 255 , 255 ).rgb(), { "://balleblanche.png", 20 }},
	{ QColor(255 , 128 , 0 ).rgb(), { "://ballepeche.png", 20 }},
	{ QColor(0 , 0 , 0 ).rgb(), { "://noir.png", 20 }},
	{ QColor(102 , 51 , 0 ).rgb(), { "://marron.png", 20 }},
	{ QColor(255 , 102 , 78 ).rgb(), { "://rose.png", 20 }},
	{ QColor(0 , 204 , 204 ).rgb(), { "://turquoise.png", 20 }},
	{ QColor(255 , 178 , 102 ).rgb(), { "://beige.png", 20 }},
	{ QColor(76 , 0 , 153 ).rgb(), { "://violet.png", 20 }},
	{ QColor(100 , 100 , 100 ).rgb(), { "://gris.png", 20 }},
};

in my .cpp

and struct in my .h,

do i paste "QMap<QRgb, CostInfo > Costs;" in my .cpp like my function or in my .h (sorry but i didnt understand ur question ^^)

mrjj

@Payx
it sounds right.

The CostInfo is in .h ?

Can you show it ?

Payx

i think i fixed it i had :

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QPixmap>
#include <QPoint>
#include <QSize>
#include <iostream>

namespace Ui {
	class MainWindow;
}

class MainWindow : public QMainWindow
{
	Q_OBJECT

public:
	explicit MainWindow(QWidget *parent = 0);
	struct CostInfo
	{
		QString ImageName;
		int     cost;
	};



	~MainWindow();





private slots:
	void on_push_clicked();
	void on_push2_clicked();

	void on_verticalSlider_sliderMoved(int position);

	void on_verticalSlider_actionTriggered(int action);

private:
	Ui::MainWindow *ui;
	QImage pixi;
	QPixmap pixa;
	float k;
	int a;


	int z=1;
	int b;
};

#endif // MAINWINDOW_H

and now i remember that i have to paste in the .h but not in public or private so i have :

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QPixmap>
#include <QPoint>
#include <QSize>
#include <iostream>

namespace Ui {
	class MainWindow;
}
struct CostInfo
{
	QString ImageName;
	int     cost;
};


class MainWindow : public QMainWindow
{
	Q_OBJECT

public:
	explicit MainWindow(QWidget *parent = 0);



	~MainWindow();





private slots:
	void on_push_clicked();
	void on_push2_clicked();


	void on_verticalSlider_sliderMoved(int position);

	void on_verticalSlider_actionTriggered(int action);

private:
	Ui::MainWindow *ui;
	QImage pixi;
	QPixmap pixa;
	float k;
	int a;


	int z=1;
	int b;
};

#endif // MAINWINDOW_H

and what is this line :

QMapIterator<QRgb, CostInfo> i;

because it say "no matching function to call"

mrjj

I wonder if you dont have c++11 compiler.

"no matching function to call"
Make sure you have included QMapIterator

Payx

i included, no change.

How can i see if i have a c++ compiler ?
