QT学习笔记之四 Sort

这几次主要练习Qt Designer的设计，所以就做了对话框，没有去做具体的实现，以后有空再写吧....哇哈哈

 

主要代码如下：

 

sortdialog.h

#ifndef SORTDAILOG_H #define SORTDAILOG_H #include #include "ui_sortdailog.h" namespace Ui { class sortdailogClass; } class sortdailog : public QDialog { Q_OBJECT public: sortdailog(QWidget *parent = 0); ~sortdailog(); void setColumnRange(QChar first,QChar last); //用来设置列的范围 private: Ui::sortdailogClass *ui; }; #endif // SORTDAILOG_H

 

sortdialog.cpp

#include "sortdailog.h" #include sortdailog::sortdailog(QWidget *parent) : QDialog(parent) { ui->setupUi(this); ui->secondaryGroupBox->hide(); //设置为隐藏 ui->tertiaryGroupBox->hide(); //设置为隐藏 this->layout()->setSizeConstraint(QLayout::SetFixedSize); //将此层设置为适合大小 setColumnRange('A','Z'); //设置默认范围*/ } sortdailog::~sortdailog() { delete ui; } void sortdailog::setColumnRange(QChar first,QChar last) { //清除原有数据 ui->primaryComboBox->clear(); ui->secondaryComboBox->clear(); ui->tertiaryComboBox->clear(); ui->secondaryComboBox->addItem(tr("None")); ui->tertiaryComboBox->addItem(tr("None")); ui->primaryComboBox->setMinimumSize(ui->secondaryComboBox->sizeHint()); //设置理想大小 QChar ch=first; while(ch<=last) { ui->primaryComboBox->addItem(QString(ch)); //QString(ch)因为tr()只能接受字符串类型 ui->secondaryComboBox->addItem(QString(ch)); ui->tertiaryComboBox->addItem(QString(ch)); ch=ch.unicode()+1; } }

 

main.cpp

#include #include "sortdailog.h" int main(int argc, char *argv[]) { QApplication a(argc, argv); sortdailog *dialog=new sortdailog; dialog->setColumnRange('C','H'); dialog->show(); return a.exec(); }

 

 

写到最后才发现我的dialog写错了..好囧啊..算了不改了
