How to include .txt on Qt

[Payx]

Yes, but correct me if i'm wrong, it could be possible that it detect many colors under 100 right ?

[mrjj]

@Payx
its a value. How high or low u need it to be , depends
on your application.

[Payx]

yes but i can't know exactly, thats why i put 100.

The things i want its the minimum of all the value

like a function who calcule all diffBlue+diffRed+diffGreen
and return me the minimum

It said that CostInfo, Costs are not declared

[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 ^^)
