如果需要按照數字排序，使用以下方法即可
定制一個項代理
class MyTableWidgetItem : public QTableWidgetItem
{
public:
MyTableWidgetItem(const QString& text):
QTableWidgetItem(text)
{
}
public:
bool operator <(const QTableWidgetItem &other) const
{
return text().toFloat() < other.text().toFloat();
}
};
調用
這樣增加數據
MyTableWidgetItem* item = new MyTableWidgetItem(QString("%1").arg(i));
table->setItem(r,l,item);
使用中點擊表頭即可排序
主要解決了很多故障，增加了一點功能
API上參考了Qt
- 支持png格式
- 支持控件序列化，反序列化
- 支持換膚
- 代碼整潔，風格良好
- 提供StackLayout,BoxLayout,GridLayout,FlowLayout
- 提供CheckBox,Panel,StaticText,ImageBox,ProgressBar,TableWidget,Slider,EditFiled,Combox等常用控件
