Qt-网易云音乐界面实现-9 照片墙功能

最近车也买了，不过倒是没有想象的那么开心，车真的是想消耗品啊。

写这个专题了，本来是想好好的磨练一下自己，不过可能要在在理就GG了。腻味了。

还是先看下效果图吧

这个照片墙还差点东西，不过我个人认为需要重写一个控件的鼠标进入事件，就可以了，懒了，这里就不写了。感兴趣的可以试试看。

这里没有技术含量。上代码吧

#include "picturewallform.h"
#include "ui_picturewallform.h"
 
int static picture_index = 2;       //当前图片索引值
PictureWallForm::PictureWallForm(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::PictureWallForm)
{
    ui->setupUi(this);
 
    QString qss_1 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index);
    QString qss_2 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index-1);
    QString qss_3 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index+1);
 
    ui->label_main->setStyleSheet(qss_1);
    ui->label_main_l->setStyleSheet(qss_2);
    ui->label_main_r->setStyleSheet(qss_3);
 
}
 
PictureWallForm::~PictureWallForm()
{
    delete ui;
}
 
void PictureWallForm::on_pushButton_plus_clicked()
{
    picture_index++;
    if(picture_index==8)
    {
        QString qss_1 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index);
        QString qss_2 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index-1);
        QString qss_3 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg("1");
        ui->label_main->setStyleSheet(qss_1);
        ui->label_main_l->setStyleSheet(qss_2);
        ui->label_main_r->setStyleSheet(qss_3);
        picture_index = 0;
    }
    else
    {
        QString qss_1 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index);
        QString qss_2 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index-1);
        QString qss_3 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index+1);
        ui->label_main->setStyleSheet(qss_1);
        ui->label_main_l->setStyleSheet(qss_2);
        ui->label_main_r->setStyleSheet(qss_3);
    }
 
}
 
void PictureWallForm::on_pushButton_subtract_clicked()
{
    picture_index--;
 
    if(picture_index==1)
    {
        QString qss_1 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index);
        QString qss_2 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg("8");
        QString qss_3 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index+1);
        ui->label_main->setStyleSheet(qss_1);
        ui->label_main_l->setStyleSheet(qss_2);
        ui->label_main_r->setStyleSheet(qss_3);
        picture_index = 8;
    }
    else
    {
        QString qss_1 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index);
        QString qss_2 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index-1);
        QString qss_3 = QString("QLabel{border-image:url(./images/picturewall/00%1.png);}").arg(picture_index+1);
        ui->label_main->setStyleSheet(qss_1);
        ui->label_main_l->setStyleSheet(qss_2);
        ui->label_main_r->setStyleSheet(qss_3);
    }
}

　　有感兴趣的，可以和我要源码。
