项目实现了九宫格炫酷主界面，下面是项目demo演示：
项目部分代码如下：
cpp
#pragma execution_character_set("utf-8")
#include "frmmain.h"
#include "ui_frmmain.h"
frmMain::frmMain(QWidget *parent) : QWidget(parent), ui(new Ui::frmMain)
{
ui->setupUi(this);
this->initForm();
}
frmMain::~frmMain()
{
delete ui;
}
void frmMain::initForm()
{
this->setWindowTitle("九宫格主界面");
bg = "main2.jpg";
QList<QToolButton *> btns = this->findChildren<QToolButton *>();
foreach (QToolButton *btn, btns) {
connect(btn, SIGNAL(clicked()), this, SLOT(buttonClick()));
}
}
void frmMain::buttonClick()
{
QToolButton *btn = (QToolButton *)sender();
QString objName = btn->objectName();
if (objName == "btnCOMTool") {
if (bg == "main1.jpg") {
bg = "main2.jpg";
} else if (bg == "main2.jpg") {
bg = "main3.jpg";
} else if (bg == "main3.jpg") {
bg = "main4.jpg";
} else if (bg == "main4.jpg") {
bg = "main5.jpg";
} else if (bg == "main5.jpg") {
bg = "main1.jpg";
}
QString qss = QString("QWidget#frm{background-image: url(:/image/%1);}").arg(bg);
qss += "QToolButton{color:#E7ECF0;background-color:rgba(0,0,0,0);border-style:none;}";
this->setStyleSheet(qss);
} else if (objName == "btnAddressTool") {
} else if (objName == "btnTCPTool") {
this->close();
} else if (objName == "btnCOMTCPTool") {
} else if (objName == "btnDefence") {
} else if (objName == "btnHostTool") {
} else if (objName == "btnLinkTool") {
} else if (objName == "btnMaiChongTool") {
} else if (objName == "btnPlot") {
} else if (objName == "btnZhangLi4Tool") {
} else if (objName == "btnZhangLi5Tool") {
} else if (objName == "btnZhangLiTool") {
}
}
