How to include .txt on Qt

so it compile but i got the 3 same errors :

QPixmap::scaled: Pixmap is a null pixmap

yep its no good

i put my code here

Because you are still trying to get the wrong entry from your map. If you enter your foreach loop, it means that colour can't be found in your map thus you can't use it to get the value from the map.

IsCloseColor tells you that BaseColor and colour are close, then you must use key to get the CostInfo you want.

Payx

Ok i understand, so it doesnt work because i still search my color in my map.

So i have to replace color by basecolor (when IsCloseColor(BaseColor, colour) == true) right ? and search for basecolor in my map ?

Flotisable

@Payx
yes

Payx

am i right if i write

CostInfo& ci = Costs[BaseColor.rgb()];

?

Flotisable

yes

by the way, you don't need to write if( IsCloseColor( BaseColor , colour ) == true ) explicitly. Yout can write if( IsColseColor( BaseColor , colour ) ) since the return value of IsCloseColor is already a bool and if can test it

Payx

Ok so it compile,

but i have the same error again :

Again checkout what you get, whether what it contains is valid.

And again 2, you are creating QLabels that will be destroyed before they can be shown.

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

So maybe write "QLabel abc;" in my .h ?

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

i have

						CostInfo& ci = Costs[BaseColor.rgb()];
						QPixmap pix( ci.ImageName );

Maybe i don't understand well this 2 lines, i explain what i understand and tell me if i'm wrong.

The first line put in my variable ci the "line" referent to my BaseColor ( it stock the Costs (who have a QString and a Int))

the second line create a pixmap from the ImageName referent to my BaseColor. So something like (QPixmap pix(:/img/ballepeche.png))

mrjj

Hi
Make sure that
BaseColor.rgb() actually give a 100% MATCH else u insert empty one with no file name and ImageName will be empty!

I think u are using it wrongly.

try
if ( Costs.contains( BaseColor.rgb()))
qDebug () << "its OK with base color";
else
qDebug () << " base color had no match!!"

before
CostInfo& ci = Costs[BaseColor.rgb()];
QPixmap pix( ci.ImageName );

As if base color is NOT 1 of the colors in qmpa, it dont work and image is empty.

Flotisable

@mrjj
@Payx's BaseColor is constructed from the key of Costs, so I think there is no problem

Payx

its OK with base color

So no problem about BaseColor !

Flotisable

@Payx
I think you can output the imageName in the foreach to check if there is a file name.

and you can try to use debug mode and execute step by step to find out which line cause the problem.

maybe it will be more clear what's wrong with it.

mrjj

Hi
Yes as @Flotisable says, you should check what is going on with the file name

so

xxxx
QPixmap pix( ci.ImageName );
qDebug() << "image i get from ci.ImageName : " << ci.ImageName;

and see what it really is.

Payx

with qDebug() << "image i get from ci.ImageName : " << ci.ImageName;

image i get from ci.ImageName :  ":/img/noir.png"
setGeometry: Unable to set geometry 8x7+640+280 on QWidgetWindow/'QLabelClassWindow'. Resulting geometry:  120x7+640+280 (frame: 8, 31, 8, 8, custom margin: 0, 0, 0, 0, minimum size: 0x0, maximum size: 16777215x16777215).

mrjj

Ok so path is good ? seems ok.
So I guess it does load it there. ( in pix)
But why does

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

still trigger then ?

or is that from
if (IsCloseColor(BaseColor, colour) == true){
xxx
}
else {
qDebug() << "yep its no good";
}

?

i replaced this line "diffBlue + diffRed + diffGreen < 100" 100 by 450 and increase the picture to a 20 * 20

its better no ?

and i had already changed into a

					if (pix.isNull()){
					qDebug() << "nothing";
					return;
					};

to see exactly where it bug

EDIT : it will not be displayed on my label, so if i put my the definition of my label in my .h doest it work?

mrjj

@Payx
Well it seems you just do
QLabel abc;
which will not work at all as this label is then deleted as soon as function ends.

Putting it in .h will help it not getting deleted but its still not connected to the screen in any way.
If you have UI file. Cant u put it there?
and get via
ui->label
Then its in the right place.

To do this, you must make Remplissage member of the mainwindow so you can acces its UI

Payx

Yes but if i create a label in my UI the picture will just be displayed in the same label no ?

mrjj

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

Yes. You can add more than one label if u need more pics to be shown at same time.
