QT: add SvgWidget to layout

Question:

Tag: qt,layout,svg

I need to create circle tiles for a board game, so I made svgWigets and tried to add them to a layout for display them.

QLayout* layout = new QVBoxLayout;
QSvgWidget tile(":/gameIcons/white.svg");
layout->addWidget(tile);

But i get this error:

error: no matching function for call to 'QLayout::addWidget(QSvgWidget&)'
layout->addWidget(tile);

I guess svgWidgets are widgets, so i don't understand why this error happens, so i'm asking for the correct form to do it, i'm a novice anyway


Answer:

You should use pointer to object, not whole object. So it should be:

QLayout* layout = new QVBoxLayout;
QSvgWidget *tile = new QSvgWidget(":/gameIcons/white.svg");
layout->addWidget(tile);

It can be also:

QLayout* layout = new QVBoxLayout;
QSvgWidget tile(":/gameIcons/white.svg");
layout->addWidget(&tile);

But in this case tile creates in stack so it can be delete in your code (from your small code snippet I can't figure out where are you using this code so the best way is to use pointer) and tile will not be valid.
