Wt

I've modified the hangman example to:

this->setMargin(Wt::WLength(0));

WVBoxLayout *layout = new WVBoxLayout();

layout->setContentsMargins(0, 0, 0, 0);

this->setLayout(layout);

images_ = new ImagesWidget();

layout->addWidget(images_, 0, AlignCenter | AlignMiddle);

m_pButtonTraining = new WPushButton("training", this);

m_pButtonFight = new WPushButton("FIGHT!", this);

m_pButtonTraining->clicked().connect(this, &WrestlingWidget::Training);

m_pButtonFight->clicked().connect(this, &WrestlingWidget::Fight);

layout->addWidget(m_pButtonTraining, 0, AlignCenter | AlignMiddle);

layout->addWidget(m_pButtonFight, 0, AlignCenter | AlignMiddle);

...

everytime I click any of the buttons I created, all lines like:

...

increase the height (%d is a dummy).

my callback functions are empty atm and it happens even when I pause the server binary, chrome reports the modification of the height attribute happens in this line:

(sorry, when I try to expand it, chrome seems to not want to debug it anymore, so I can't be more precise)
