How to include .txt on Qt

Payx

so in this loop

  for(int x = topLeft.x(); x < maxX; ++x) {
    for(int y = topLeft.y(); y < maxY; ++y) {

i can include

QLabel *label = new QLabel(this);
      foreach( QRgb key, Costs.keys() ) {
        QColor BaseColor( key );
        if (Costs.contains( colour.rgb() ) || IsCloseColor(BaseColor, colour) )  {
          CostInfo& ci = Costs[colour.rgb()];
//          int Cost = ci.Cost;
          QPixmap pix( ci.ImageName );
					QPixmap scaledPix = pix.scaled(   8, 8,
																				 Qt::KeepAspectRatio,
																				 Qt::SmoothTransformation
																				 );

ui->label->setPixmap(pix);

?

mrjj

@Payx
yes something like that.
if pix is the FINISHED result. seems not.

That code would just show the original one?

and why new the qlabel? Why not just add to UI file with designer?

Payx

Because it will not return only one picture, if my picture is 540540 and my rectangle is 88 i cannot just add a label to display 70 picture.

at the end it will have http://www.hostingpics.net/viewer.php?id=354728program.png

by replacing all the rectangle by a picture, it depends the color of the rectangle

@ambershark Lol

I prefer learn instead of just don't understand what i'm doing, i know i'm very bad to programmation by now but maybe in few years i'il be like mrjj haha !

Haha it's good that you are learning instead of asking for it done like a lot of people on these forums. And hey we all started out bad, don't worry you'll be good in no time if you stick with it. ;)

I was just quite impressed with the number of posts in this topic.

Payx

@ambershark No problem ^^!

Payx

This post is deleted!

Payx

I tried something without you (sorry ahah)

QLabel abc;
abc.setPixmap(scaledPix);
abc.show();

it compiles but there is a error : QPixmap::scaled: Pixmap is a null pixmap

mrjj

@Payx said in How to include .txt on Qt:

scaledPix

Sounds like scaledPix is not initialize as it should , which often
comes from not being able to load a file.

Make sure the image you are scaling, is indeed valid. (loaded)

Payx

Before posting, i've tried to just

QPixmap pix(":/img/ballebleue.png")
ui->setPixmap .....

and it works

u said "scaledPix is not initialize as it should ?"

EDIT : Happy New Year !

mrjj

@Payx

Yes That would make the pix valid.

To get the error " Pixmap is a null pixmap" for scaledPix means that
it was not valid. It was empty. so if it came from a scale function, it means
that the image u scaled to get scaledPix was empty.

Happy new Year :)

Payx

					QLabel abc;
//          int Cost = ci.Cost;
					QPixmap pix( ci.ImageName );
					QPixmap scaledPix = pix.scaled(   8, 8,
																				 Qt::KeepAspectRatio,
																				 Qt::SmoothTransformation
																				 );
					abc.setPixmap(scaledPix);
					abc.show();

i have this :

so the error come from "QPixmap pix" who is empty

so the line "QPixmap pix( ci.ImageName );" dont create a pixmap from my QMap ?

mrjj

QPixmap pix( ci.ImageName );" dont create a pixmap from my QMap ?

That would be my guess yes.

You can check pix with isNull()

Payx

So i add the if :

					if (pix.isNull()){
					QPixmap pix(":/img/ballebleue.png");
					};

Same error as before "QPixmap::scaled: Pixmap is a null pixmap"

mrjj

@Payx said in How to include .txt on Qt:

if (pix.isNull()){
QPixmap pix(":/img/ballebleue.png");
};

Well that would not really change anything as you create a new local pix and its not related to the "pix" outside
You should find out if its invalid and then why it is

if (pix.isNull()){
qDebug() << "yep its no good";
return;
};

Payx

okay so i have that.

that's mean that my pix is null right?

mrjj

@Payx
Yes this means that the pictures in the table cannot be loaded.
Are they in a resource ?

Payx

Yes i have that exactly :http://hpics.li/cc11b5c

mrjj

@Payx
Oh, they are under IMG

Right click one image file.
Find Get Path
should be something like

:/IMG/filename.xxx

Fix the names in the table.
As far as i recall they start like ":/filename.xxx" and that dont match.

alt text

Note: Here i do NOT have them in a sub folder like you have (img) so path is :/p1.png

Payx

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

i didnt mention that but i had already changed the path

mrjj

@Payx
oh, it seems correct. You checked they are truly correct?

Please qDebug() << ci.ImageName to verify the variable contains the path from
the table.

just above where you try to make pixmap

qDebug() << "check me--->" << ci.ImageName;
QPixmap pix( ci.ImageName );
