QT学习笔记之十一 SymbolPicker

最近太忙了，都没怎么看Qt鄙视下自己....

 

不说了，放代码

 

============================================================

symbolpicker.h

#ifndef SYMBOLPICKER_H#define SYMBOLPICKER_H#include <QtGui/QDialog>#include <QMap>class QDialogButtonBox;class QIcon;class QListWidget;namespace Ui{ class SymbolPicker;}class SymbolPicker : public QDialog{ Q_OBJECTpublic: SymbolPicker(const QMap<int,QString> &symbolMap,QWidget *parent = 0); ~SymbolPicker(); int selected() const {return id;} void done(int result);private: Ui::SymbolPicker *ui; QIcon iconForSymbol(const QString &symbolName); QListWidget *listWidget; QDialogButtonBox *buttonBox; int id;};#endif // SYMBOLPICKER_H

 

 

symbolpicker.cpp

#include<QtGui>#include "symbolpicker.h"#include "ui_symbolpicker.h"SymbolPicker::SymbolPicker(const QMap<int,QString> &symbolMap,QWidget *parent) : QDialog(parent), ui(new Ui::SymbolPicker){ ui->setupUi(this); id = -1; //设置id默认值 listWidget = new QListWidget; listWidget->setIconSize(QSize(60,60)); QMapIterator<int,QString> i(symbolMap); while(i.hasNext()) { i.next(); QListWidgetItem *item = new QListWidgetItem(i.value(),listWidget); item->setIcon(iconForSymbol(i.value())); item->setData(Qt::UserRole,i.key()); } buttonBox = new QDialogButtonBox(QDialogButtonBox::Ok| QDialogButtonBox::Cancel); connect(buttonBox,SIGNAL(accepted()),this,SLOT(accept())); connect(buttonBox,SIGNAL(rejected()),this,SLOT(reject())); QVBoxLayout *layout = new QVBoxLayout; layout->addWidget(listWidget); layout->addWidget(buttonBox); setLayout(layout); setWindowTitle(tr("Symbol Picker"));}SymbolPicker::~SymbolPicker(){ delete ui;}void SymbolPicker::done(int result){ id = -1; if (result == QDialog::Accepted) { QListWidgetItem *item = listWidget->currentItem(); if (item) id = item->data(Qt::UserRole).toInt(); } QDialog::done(result);}QIcon SymbolPicker::iconForSymbol(const QString &symbolName){ QString fileName = ":/images/" + symbolName.toLower(); fileName.replace(' ','-'); return QIcon(fileName);}

刚开始icon显示一直有问题，后来配置了下资源文件就OK了...
