設置QPushbutton按鈕背景、鼠標滑過狀態、鼠標點擊后狀態用法

1.1當要設置QPushbutton按鈕背景，字體顏色，鼠標滑過狀態，鼠標單擊后狀態時，可以用QSS來設置，具體的代碼如下：

    QPushButton *allSelect = new QPushButton;
    allSelect->setStyleSheet("QPushButton{border-image: url(:/res/appicon/wx.png) 0 0 0 0;border:none;color:rgb(255, 255, 255);}"
                            "QPushButton:hover{background-color: rgb(20, 62, 134);border:none;color:rgb(255, 255, 255);}"
                            "QPushButton:checked{background-color: rgb(20, 62, 134);border:none;color:rgb(255, 255, 255);}");

1.2另一種設置按鈕圖標顯示。下面代碼功能是在一個按鈕內顯示圖標和文字，效果為左圖標，右文字。當鼠標滑過時圖標切換為另一個圖標。當點擊鼠標后又切換到另一個圖標。具體代碼如下：

    QPushButton *readyRecoveryBtn = new QPushButton("准備恢復");
    readyRecoveryBtn->setFixedSize(QSize(95,20));
    readyRecoveryBtn->setStyleSheet("QPushButton{background-image: url(:res/recoverydata/icon/main_icon_recovery.png);background-repeat: no-repeat;background-position:left;border:none;color:rgb(255, 255, 255);}"
                                "QPushButton:hover{background-image: url(:res/recoverydata/icon/main_icon_recovery_h.png);background-repeat: no-repeat;background-position:left;border:none;color:rgb(255, 255, 255);}"
                                "QPushButton:pressed{background-image: url(:res/recoverydata/icon/main_icon_recovery_p.png);background-repeat: no-repeat;background-position:left;border:none;color:rgb(255, 255, 255);}");
