自制虚拟键盘Demo

最近调用系统键盘的时候有些时候系统的键盘并不满足需求，所以做了个小Demo

先看一下效果：

 

看一下核心代码：

#include "skeyboard.h"

SKeyboard::SKeyboard(QWidget *parent) : QWidget(parent)
{
    for(int i = 0; i < 43; i++) {
        QPushButton* tmp_btn = new QPushButton(this);
        tmp_btn->setStyleSheet("QPushButton{border-image:url(:/blue.png);} \
                                QPushButton::hover {border-image:url(:/blue_hover.png);} \
                                QPushButton::pressed {border-image:url(:/blue_press.png);}");
        connect(tmp_btn, &QPushButton::clicked, [=]{
            emit sigKeyPress(tmp_btn->text());
        });
        m_keys << tmp_btn;
    }
    this->resetKeyPosSize();
    this->resetText();
}

void SKeyboard::resetText()
{
    for(int i = 0; i < 10; i++) {
        m_keys.at(i)->setText(QString::number((i + 1) == 10 ? 0 : (i + 1)));
    }
    m_keys.at(10)->setText("Back Space");
    m_keys.at(11)->setText("Q");
    m_keys.at(12)->setText("W");
    m_keys.at(13)->setText("E");

    m_keys.at(32)->setText("X");
    m_keys.at(33)->setText("C");
    m_keys.at(34)->setText("V");
    m_keys.at(35)->setText("B");
    m_keys.at(36)->setText("N");
    m_keys.at(37)->setText("M");
    m_keys.at(38)->setText("@");
    m_keys.at(39)->setText("Left");
    m_keys.at(40)->setText("Right");
    m_keys.at(41)->setText(".com");
    m_keys.at(42)->setText("Enter");
}

void SKeyboard::resetKeyPosSize()
{
    //1
    for(int i = 0; i < 10; i++) {
        m_keys.at(i)->resize(55, 55);

    }
    //3
