How to make a SVG at tab Widget ?

[jsulm]

@RiceBall OK, no problem.
The second line should print something to the console - what do you see there ("Application Output" tab in QtCreator)?

Do I add code at customwidget.cpp is right ??
I can't see any QDebug message.

@RiceBall Are you sure you create an instance of customwidget? Because I don't see the output of qDebug().

Hi
I had a quick look.
several things:
1:

you have another CustomWidget that you use. its not the one with the svg files. its pretty empty.
delete it.

2:
Use your actual widget. Notice the class name is with all small letters and you used one with mixed. the empty class.

This has to be

customwidget *csw = new customwidget; <<<<< notice small letters.

3:
Your paths are wrong, or you are not using the resources.

Right click the files in the left side project view and use the get path function there. then its always correct.
4:
Then it will show. (profit)

Thank you for @jsulm help.
It looks like not very easy for me to debug it.
I need to learning more and more.

final problem.
My loading picture want to overlap together.(Now is not)
How to coding it ??

[mrjj]

Hi
well learning to use the debugger is a must do as that find such error.
I saw the empty class by stepping into the code with f10.
So with debugger, it was not hard to find.

Anyway,
They are not on top of each other
as you put them in layout.

So you can drop the layout

customwidget::customwidget(QWidget *parent) : QWidget(parent)
{
    //QGridLayout *glyt = new QGridLayout;

    QSvgWidget *svgWid1 = new QSvgWidget(":/resource/splash1.svg", this);
    QSvgWidget *svgWid2 = new QSvgWidget(":/resource/splash2.svg", this);
    //       QSvgWidget *svgWid3 = new QSvgWidget("../iHMI_2/splash3.svg");
    //       QSvgWidget *svgWid4 = new QSvgWidget("../iHMI_2/splash4.svg");

    //glyt->addWidget(svgWid1);
    //glyt->addWidget(svgWid2);
    //glyt->addWidget(svgWid2);
    //glyt->addWidget(svgWid3);
    //glyt->addWidget(svgWid4);

    svgWid1->show();

    qDebug() << svgWid1->renderer()->isValid();

    //this->setLayout(glyt);

}

However, im not 100% sure on what the goal is with the 3 SVG and the "Loading" one so
it might not be what you really want.

Finally, I did it.
Thank you for your patient answer.

The last question , my background is set to black color.
And My SVG file is transparent.
How could I set scene background to black ?
I have set "scene->setBackgroundBrush(Qt::black);"

[mrjj]

Hi
\0/
You can ask widget to be transparent. You are seeing the customwidget.
( in mainwin)
customwidget *csw = new customwidget;
csw->setAttribute(Qt::WA_NoSystemBackground, true); // add this

@mrjj
Thank you very much.
I did it.
I will learn hardly.
