How to include .txt on Qt

Payx · 1 Sept 2017, 13:46

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

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

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

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

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

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))

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.

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

Payx · 9 Jan 2017, 14:37

its OK with base color
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).

So no problem about BaseColor !

Flotisable · P Payx 9 Jan 2017, 14:26

@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 · 1 Sept 2017, 14:39

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 · 1 Sept 2017, 14:45

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).

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";
}

?

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 · P Payx 9 Jan 2017, 14:52

@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 · 9 Jan 2017, 16:07

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

mrjj · P Payx 9 Jan 2017, 15:41

@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.

Payx · wrote on 9 Jan 2017, 16:28

my funtion is

void Remplissage(QImage& image, const QPoint& topLeft, const QSize& rectangle, const QColor& colour) {

   int maxX = topLeft.x() + rectangle.width();
   int maxY = topLeft.y() + rectangle.height();

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

in

Remplissage(pixi, QPoint(i, j), QSize(z, z), Couleurdominante(pixi, QPoint(i, j), QSize(z, z)));

so it depends on my z, if i say that my z = 20; and if my picture is 540 * 540 i will need 729 labels lol.

example :

here my previous code : http://hpics.li/36d1f82

my picture is 128 * 128, if my z = 28; it appears 4 colors by 4 colors.

How can i display a picture by color without add 10000 labels, thats why i though that create a label in my loop will work

SGaist · wrote on 9 Jan 2017, 21:40

Create a new image and put it into a secondary QLabel.

Payx · 1 Oct 2017, 09:56

Something like :
QImage from pix
And put the image into a label ?

I know that put a label into a loop wont work u told me. But how can i do so ?

Payx · 1 Oct 2017, 16:24

nobody know how to ?

or maybe an other way, if its too complicated ^^

mrjj · P Payx 10 Jan 2017, 16:21

@Payx
You lost me on what you are trying with the Labels. 729 ?!?!
Do you mean to have the lables like

or how would you place all these labels?

Payx · 10 Jan 2017, 16:56

label is not obligatory, it's just me with my few knowlegde that i said i can use labels.

but the problem is that i have to replace the color by the picture (replace or add) and its here that i'm blocked

mrjj · 1 Oct 2017, 16:57

@Payx
on top of the "red" image ? so that each cell is an image?

Payx · 1 Nov 2017, 01:02

yes each cell is an image.

on the picture that you showed there is 16 cell so 16 picture who depend on the color

Edit : we had before "image.setPixelColor(x, y, colour);"

can't we have like image.'setImage' or something?
