How to include .txt on Qt

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 ?

mrjj

@Payx
Ok. No sure what goes wrongly for you. Seems to have CostInfo
in .h and Costs QMap in cpp which should be fine.

How can i see if i have a c++ compiler ?
c++11 compiler. Meaning a compiler that knows the new c++11 version.
I assume you do. But if you are on linux or using old Qt it might not be the case.

So what platform and Qt version?

Payx

i paste for you all my project so you can see exactly :

I am on windows 10
Qt 4.1.0

mrjj

It looks ok.
What is the exact error you get?

Also 4.1 is very old. Are you using old mingw too?

Old compilers might not like the initialisation list/in place
If you just do
QMap<QRgb, CostInfo > Costs;

Will it compile then?

Payx

i added

QMap<QRgb, CostInfo > Costs;

In mainwindow.cpp

and my error is !

![http://hpics.li/b0d194a](image url)

with only QMap ... it compile

SGaist

QMapIterator<QRgb, CostInfo> i; is wrong

It should be something like

QMap<QRgb, CostInfo>::const_iterator i = Costs.constBegin();
while (i.hasNext()) {
//etc.
}

Payx

@SGaist Thank you ! i think it works

![http://hpics.li/8a8e235](image url)

i don't know how to solve the 3 first error
