介绍

tpHBoxLayout 类 水平布局管理器 tpHBoxLayout 可以使子组件在水平方向排成一行，它将所有的组件分成一行盒子，然后将每一个组件放入一个盒子中。

使用示例

tpDialog *floatScreenH = new tpDialog();
floatScreenH->setBackGroundColor(_RGBA(255, 255, 255, 200));
floatScreenH->setRect(0, 0, 900, 600);
floatScreenH->setAlpha(128);
floatScreenH->setBeMoved(true);

tpHBoxLayout *hLayout = new tpHBoxLayout();
hLayout->setDirection(tpBoxLayout::RightToLeft);

tpVBoxLayout *sonLayout = new tpVBoxLayout();
sonLayout->setContentsMargins(0, 0, 0, 0);

tpHBoxLayout *son2Layout = new tpHBoxLayout();
son2Layout->setContentsMargins(0, 0, 0, 0);

for (int i = 0; i < 4; ++i)
{
    tpButton *testButton = new tpButton("测试按钮" + tpString::number(i));
    tpButton *testButton3 = new tpButton("子按钮" + tpString::number(i));
    tpButton *testButton4 = new tpButton("二级子按钮" + tpString::number(i));

    testButton->setMinimumSize(100, 40);
    testButton3->setMinimumSize(100, 40);
    testButton4->setMinimumSize(100, 40);

    testButton->setBackGroundColor(_RGB(255, 15, 15));

    hLayout->addWidget(testButton, i + 1);

    sonLayout->addWidget(testButton3, i + 1);
    son2Layout->addWidget(testButton4, i + 1);
}
sonLayout->addLayout(son2Layout);
hLayout->addLayout(sonLayout, 3);

hLayout->addSpacer(new tpSpacerItem(100, 20, tpSpacerItem::Expanding, tpSpacerItem::Minimum));

floatScreenH->setLayout(hLayout);
