效果演示
使用方法
将 slidenavigation.cpp 和 slidenavigation.h 添加到项目里面
在UI设计师界面拖动一个Widget控件
右键选择 提升为...，填写提升的类名称为 SlideNavigation，如下所示
右键 提升为 选择刚刚添加的类 SlideNavigation 。
控件使用
控件属性
//#define YELLOW //黄色
//#define RED //红色
//#define PURPLE //紫色
#define GREEN //绿色
修改属性
ui->widget->addItem("星期一");ui->widget->addItem("星期二");ui->widget->addItem("星期三");ui->widget->addItem("星期四");ui->widget->addItem("星期五");ui->widget->addItem("星期六");ui->widget->addItem("星期日");ui->widget->addItem("星期八");ui->widget->setBarRadious(5); //设置Widget的圆角ui->widget->setItemRadious(5); //设置Item的圆角ui->widget->setFixed(true); //设置固定#if defined YELLOW //黄色ui->widget->setItemStartColor(QColor(254, 176, 42));ui->widget->setItemEndColor((QColor(225, 156, 37)));
#elif defined RED //红色ui->widget->setItemStartColor(QColor(255, 0, 0));ui->widget->setItemEndColor((QColor(225, 20, 10)));
#elif defined PURPLE //紫色ui->widget->setItemStartColor(QColor(191, 65, 249));ui->widget->setItemEndColor((QColor(187, 83, 217)));
#elif defined GREEN //绿色ui->widget->setItemStartColor(QColor(62, 139, 6));ui->widget->setItemEndColor((QColor(40, 139, 28)));
#else//默认灰底蓝色
#endif
控件信号
点击的控件下标
signals:void itemClicked(int index, QString str);
关联信号与槽
connect(ui->widget,SIGNAL(itemClicked(int, QString)),this,SLOT(_SlotCheckedMenu(int, QString)));
槽函数打印
void Widget::_SlotCheckedMenu(int index, QString name)
{qDebug()<<"index:"<<index<<" ,name"<<name;
}
主要代码已经扣过来了，可以直接复制代码到项目中去。
