问题描述

我想让一个名为显示字幕的QCheckBox禁用另一个名为显示标题,如果没有标题的QCheckBox,当我第一次被选中,但我的问题是,如果我能够立即禁用,当用户选中第一个复选框。

I want to make a QCheckBox named "Show Captions" disable another QCheckBox named "Show captions if no title" when the first is checked, but my problem is that how I can make it disabled immediately when the user checks the first checkbox.

SetupSlideShow::SetupSlideShow(QWidget* parent)
    : QScrollArea(parent), d(new SetupSlideShowPriv)
{
    QWidget* panel = new QWidget(viewport());
    setWidget(panel);
    setWidgetResizable(true);

    QVBoxLayout* layout = new QVBoxLayout(panel);

    d->showComment = new QCheckBox(i18n("Show captions"), panel);
    d->showComment->setWhatsThis( i18n("Show the image caption at the bottom of the screen."));

    d->showTitle = new QGroupBox(i18n("Show title"), panel);
    d->showTitle->setWhatsThis( i18n("Show the image title at the bottom of the screen."));
    d->showTitle->setCheckable(true);

    d->showCapIfNoTitle = new QCheckBox(i18n("Show captions if no title"), panel);
    d->showCapIfNoTitle->setWhatsThis( i18n("Show the image caption at the bottom of the screen if no titles existed."));
    QVBoxLayout *vbox = new QVBoxLayout;
    vbox->addWidget(d->showCapIfNoTitle);
    d->showTitle->setLayout(vbox);
    layout->addWidget(d->showLabels);
    layout->addWidget(d->showComment);
    layout->addWidget(d->showTitle);
}
