How to include .txt on Qt

[SGaist]

You should cleanup the casing of your variables and class member calls.

[Payx]

How clean up all ?

[Flotisable]

@Payx
in your definition of CostInfo, your variable is named cost not Cost

the member hasNext and next belong to QMapIterator, not QMap::iterator
read the document of QMapIterator and QMap::iterator for more information

[Payx]

So the line

QMapIterator<QRgb, CostInfo> i(Costs);

Is correct ?
""
What is a redefinition of a QMap ? because it say that i have a redefinition of ""QMap<QRgb, CostInfo > Costs""

Hi
I move the code around so it compiled here.
https://www.dropbox.com/s/1z7lzjk4fqwxslz/mycolortest.zip?dl=0
Also change QMapIterator to a for each loop to get rid of QMapIterator.

If you get any errors from this it, please list them exactly.

[Payx]

Thanks it compile,

the problem is that my window crash when i push the boutton who execute
" Remplissage(pixi, QPoint(i, j), QSize(z, z), Couleurdominante(pixi, QPoint(i, j), QSize(z, z)));
"
^^

maybe enough things to do ?

[mrjj]

Well since you know what function it is, simply set a break point and single step through the code.
That way it will clearly show what line it crashes on. ;)

[Payx]

It's not crash, the program run at infinity and do nothing

[mrjj]

@Payx
well that will also be really clear from single stepping :)

[Payx]

I placed breakpoint on

  for(int x = topLeft.x(); x < maxX; ++x) {
    for(int y = topLeft.y(); y < maxY; ++y) {
      image.setPixelColor(x, y, colour);

      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 );
        }

because its new and before it worked.

And nothing who looks like a crash happened. So i don't understand, maybe it is just a big picture (540 * 540) and the app have difficult to do the code

EDIT : i tried to increase the rectangle size, it worked.

but dont replace the color by a picture

and it say that int cost is an unused variable

[mrjj]

Hi
In the inner
CostInfo& ci = Costs[colour.rgb()];
int Cost = ci.Cost; // not used for anything
QPixmap pix( ci.ImageName ); // not used for anything
}

it was just for getting the data from the Costs qmap.
You still need to code what ever you want to do with it :)
Currently it just check if color is a match and even if yes, then nothing.

[Payx]

so if i understood well

int Cost = ci.Cost; /// the Cost in my Qmap
QPixmap pix( ci.ImageName ); /// the picture into a Pixmap

The problem is that the rectangle that i use to calcul the DominantColor isn't a Label or something, so how can i replace a picture into a virtual rectangle ?

[mrjj]

@Payx
Yes those are the values from the qmap.

• so how can i replace a picture into a virtual rectangle

Sorry but Im not sure what kind of operation you want to do.
For each dominánt color for an area. you want to paint all of that area
with this color? Like paint 0,0,40,40 with same color. ?

[Payx]

My program already do that :

http://hpics.li/c00cce7

but what i want is that for each rectangle that my picture have, it will replace this rectangle of color by a picture in my QMap (like if the rectangle's color is near the red, it will replace by the picture fraise.png and add a Cost)

[mrjj]

@Payx
You mean that the red squares would be pictures instead?
The painter has drawPixmap
http://doc.qt.io/qt-5/qpainter.html#drawPixmap
You can fit the image to the rect.

[Payx]

All square would be picture, the picture depends of the color.

If its red we see in the QMap that the picture is fraise.png
if its green -> balle verte.png

i think i dont need "QRectF target" or "source"

because i have already this

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

when im on the for i'm already in the square.

[mrjj]

ok. that sounds fine.
I assume you need to scale the pictures down to fit in the
area. ?
You can use scaled function.

QPixmap scaledPix = pix.scaled(   WIDTH, HEIGHT
                               Qt::KeepAspectRatio,
                               Qt::SmoothTransformation
                               );

painter.drawPixmap(QPoint(), scaledPix);

[Payx]

So i have to rezise the picture or it will do automaticaly ?

i don't understand what the function do

[mrjj]

No, you will have to resize it, else it will be exactly as in the file.( I assume too big)
the scaled function returns a copy of the pixmap that is scaled to
WIDTH, HEIGHT. so it will fit in your area.

[Payx]

so if my rectangle is 8*8 tell me if it's correct :

QPixmap scaledPix = pix.scaled(   8, 8
                               Qt::KeepAspectRatio,
                               Qt::SmoothTransformation
                               );

painter.drawPixmap(QPoint(i,j), scaledPix);

just that ?
