How to include .txt on Qt

Payx · 7 Jan 2017, 17:58

So i add the if :

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

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

@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;
};

that's mean that my pix is null right?

mrjj · replied to Payx on 7 Jan 2017, 18:07

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

Payx · 7 Jan 2017, 18:11

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

mrjj · 1 Jul 2017, 18:15

@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.

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

i didnt mention that but i had already changed the path

mrjj · 1 Jul 2017, 18:19

@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 );

Payx · 7 Jan 2017, 18:34

I have

check me---> ""

so there is nothing

i declared as QString ImageName
so maybe it is that ?

mrjj · replied to Payx on 7 Jan 2017, 18:34

@Payx
Not sure. check the code that look it up.
If from table it should not be empty :)

SGaist · wrote on 7 Jan 2017, 18:35

Are you sure you are retrieving a valid value from your map ?

Payx · 1 Jul 2017, 18:41

No it's sure that it's not a valid value !

QPixmap pix( ci.ImageName );

so it create a pix from a QString no ? that why it didnt work ?

SGaist · wrote on 7 Jan 2017, 18:52

From what you wrote before, ci.ImageName is empty, correct ?

If so, check the key that you use to retrieve the data from the map. If not part of the map, depending on the technique used, you will get a default constructed object.

Payx · wrote on 7 Jan 2017, 19:15

Yes it's empty.

			foreach( QRgb key, Costs.keys() ) {
				QColor BaseColor( key );
				if (Costs.contains( colour.rgb() ) || IsCloseColor(BaseColor, colour) )  {
					CostInfo& ci = Costs[colour.rgb()];
					QLabel abc;
//          int Cost = ci.Cost;
					qDebug() << "check me--->" << ci.ImageName;
					QPixmap pix( ci.ImageName );
					if (pix.isNull()){
					qDebug() << "yep its no good";
					return;
					};
					QPixmap scaledPix = pix.scaled(   8, 8,
																				 Qt::KeepAspectRatio,
																				 Qt::SmoothTransformation
																				 );
					abc.setPixmap(scaledPix);
					abc.show();

it's what i have.

SGaist · wrote on 7 Jan 2017, 21:07

Your logic is flawed. If Costs contains colour.rgb() then you can go on with the rest of your logic else you should go through your map and use IsCloseColor to determine which key is good. Then you can use that key to go further.

Payx · wrote on 7 Jan 2017, 21:47

So i have to separate the

colour.rgb() ) || IsCloseColor(BaseColor, colour)

?

can you tell me how can i got through my map i've already search and asked but no one answer

SGaist · wrote on 7 Jan 2017, 22:24

You're already doing it with your foreach loop and the documentation of QMap shows several ways of looping through its content.

Payx · wrote on 7 Jan 2017, 22:35

something like that ?

			foreach( QRgb key, Costs.keys() ) {
				QColor BaseColor( key );
				if (Costs.contains( colour.rgb() ))  {
					CostInfo& ci = Costs[colour.rgb()];
					QLabel abc;
//          int Cost = ci.Cost;
					qDebug() << "check me--->" << ci.ImageName;
					QPixmap pix( ci.ImageName );
					if (pix.isNull()){
					qDebug() << "yep its no good";
					return;
					};
					QPixmap scaledPix = pix.scaled(   8, 8,
																				 Qt::KeepAspectRatio,
																				 Qt::SmoothTransformation
																				 );
					abc.setPixmap(scaledPix);
					abc.show();

				}
				else {
					if (IsCloseColor(BaseColor, colour) == true){
						CostInfo& ci = Costs[colour.rgb()];
						QColor BaseColor( key );
						QPixmap pix( ci.ImageName );
						QPixmap scaledPix = pix.scaled(   8, 8,
																					 Qt::KeepAspectRatio,
																					 Qt::SmoothTransformation

						abc.setPixmap(scaledPix);
						abc.show();
					}
					else {
						qDebug() << "yep its no good";
					}
				}

SGaist · wrote on 7 Jan 2017, 22:41

Move the foreach loop in the else part. There's no sense in looping through the whole map if it contains colour.rgb(). Also note that you won't see any QLabel since it's going out of scope.
