C++ (Cpp) unlockChild Examples

Example #1

File: uiwidget.cpp Project: Pucker/otclient

void UIWidget::lockChild(const UIWidgetPtr& child)
{
    if(m_destroyed)
        return;

    if(!child)

    // prevent double locks
    if(isChildLocked(child))
        unlockChild(child);

    // disable all other children
    for(const UIWidgetPtr& otherChild : m_children) {
