在看 main.cpp

#include <QDialog> #include <QApplication> #include <QGridLayout> #include <QPushButton> #include <QLineEdit> #include <QFileDialog> #include <QFontDialog> #include <QColorDialog> #include "standar<a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>.h" standar<a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>::standar<a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>(QWidget *parent):QDialog(parent){ //设置窗口标题 setWindowTitle("StanDarDialog"); //实例化布局管理器 gridLayout=new QGridLayout(this); //设置按钮和输入框 fontButton=new QPushButton("font Button"); <a class="tags" href="/tags/FILE.html" title=file>file</a>Button =new QPushButton("<a class="tags" href="/tags/FILE.html" title=file>file</a> Button"); colorButton=new QPushButton("color Button"); <a class="tags" href="/tags/FILE.html" title=file>file</a>LineEdit=new QLineEdit(this); fontLineEdit=new QLineEdit(this); fontLineEdit->setText("font line edit"); //实例一个<a class="tags" href="/tags/KuangJia.html" title=框架>框架</a> FRAME colorFrame =new QFrame; colorFrame->setFrameShape(QFrame::Box); colorFrame->setAutoFillBackground(true); gridLayout->addWidget(<a class="tags" href="/tags/FILE.html" title=file>file</a>Button,0,0); gridLayout->addWidget(<a class="tags" href="/tags/FILE.html" title=file>file</a>LineEdit,0,1); gridLayout->addWidget(colorButton,1,0); gridLayout->addWidget(colorFrame,1,1); gridLayout->addWidget(fontButton,2,0); gridLayout->addWidget(fontLineEdit,2,1); //设置间距 gridLayout->setMargin(5); gridLayout->setSpacing(10); //关联信号和槽 connect(fontButton,SIGNAL(clicked()),this,SLOT(slotOpenFontDlg())); connect(<a class="tags" href="/tags/FILE.html" title=file>file</a>Button,SIGNAL(clicked()),this,SLOT(slotOpenFileDlg())); connect(colorButton,SIGNAL(clicked()),this,SLOT(slotOpenColorDlg())); //设置布局管理器 setLayout(gridLayout); } //颜色 对话框 void standar<a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>::slotOpenColorDlg(){ QColor color=QColorDialog::getColor(); if(color.isValid()){ colorFrame->setPalette(QPalette(color)); } } //文件对话框 void standar<a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>::slotOpenFileDlg(){ QString <a class="tags" href="/tags/FILE.html" title=file>file</a>name=QFileDialog::getOpenFileName(this,"open this <a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>","/"); <a class="tags" href="/tags/FILE.html" title=file>file</a>LineEdit->setText(<a class="tags" href="/tags/FILE.html" title=file>file</a>name.toAscii()); } //字体对话框 void standar<a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>::slotOpenFontDlg(){ bool ok; QFont font=QFontDialog::getFont(&ok); if(ok){ fontLineEdit->setFont(font); } } int main(int argc,char ** argv){ QApplication app(argc,argv); standar<a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a> <a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>; <a class="tags" href="/tags/DIALOG.html" title=dialog>dialog</a>.show(); return app.exec(); }
