[SOLVED]can not declare QIcon in class?

vinb

Hi all,

I have a "strange" problem.
I want to declare a QIcon in my header file(class) and set its filename in the constructor.
But when i add "QIcon icon;" in my class, the program crashes when started.
When i add "QIcon icon" in a constructor/function it works as it should be.

Can someone please explain if im doing something wrong here?

Franzk

uh. Show some code?

vinb

Ok,

In .h:
@
private:
QIcon icon; //makes the program crash.
OR
QIcon *icon//also crashes.
@

In a normal function it works like a charme.

Just for kicks, change the name to m_icon and see what happens.

Obviously it isn't just the fact that you do @QIcon *icon@ in some header. There is more to this. The code snippet you showed is just as good as the description you gave. If the above doesn't work, we will need a lot more context to the problem.

can you produce a small example with this problem? (only a small class with QIcon)

Hi Franzk,

I'm sorry if i'm not clear here, so i try to explain myself a little better now.

I'm writing a little test program where i want to have a icon shown in a listview.

if i use a function call like:
@ QStandardItem *item = new QStandardItem;
item->setIcon(QIcon(":/icon/pic5"));@
then everything works like a charme.
If i do :
@ QStandardItem *item = new QStandardItem;
QIcon proeficon(":/icon/pic5");
item->setIcon(proeficon);@
everything works like a charme.
If i do:
@ QStandardItem *item = new QStandardItem;
QIcon proeficon;
proeficon.addFile(":/icon/pic5");

item->setIcon(proeficon);@

everything works like a charme.

But if i do:

In header:
@
QIcon proeficon;
@
And in the constructor:
@
proeficon.addFile(":/icon/pic5");@
Then my program crashes.

I hope i did explain it better now?

Paste a complete, small, compilable testacase.

Recall:
i just made a small example with only a qicon in the class, but the problem didnt accure.
So i have to puzzle a little bit more, to narrow the problem down.

Solved:
Very strange,
I just copied the whole class to another one and it worked like expected. So there was nothing wrong with the code.
So i deleted the whole build folder to force creator to build again and everything worked perfectly after that.
Does somebody know what was going on here?

Franzk

Sometimes you just need to rebuild...

i thought that i had done that, but clearly not
