1. U++ 中涉及字符串的函数

Posted by haifeng on 2021-06-17 22:51:22 last update 2021-06-17 22:52:26 | Answers (0) | 收藏


tmpstr 存储了文件名, 现在检查其是否以 ".mp3" 结尾, 可以使用 EndsWith() 函数

if(tmpstr.Find(strToFind)+4==tmpstr.GetLength())
if(tmpstr.EndsWith(".mp3"))

与之对应, 检查tmpstr是否以某字符串作为开头, 可以使用 StartWith()函数.

GetLength() 与 GetCount() 是同义的, 计算其中含有字符的个数.  类似于 std::string 中的 size() 或 length() 函数.

2. U++中的主函数

Posted by haifeng on 2021-04-11 15:36:19 last update 2021-04-11 15:36:19 | Answers (0) | 收藏


U++中的main函数形如

GUI_APP_MAIN
{
App::App().Run();
}
 
事实上, 这里 GUI_APP_MAIN 是一个宏, 定义在 U++Framework/upp/uppsrc/CtrlCore/CtrlCore.defs 中. 内容为:

#define GUI_APP_MAIN  void GUI_APP_MAIN()

3. Upp 的 core.h 中重复加载 math.h

4. Upp 中的一些函数简介

Sizeable().Zoomable();//Sizeable()使得应用程序界面可以调整大小, Zoomable()使得应用程序界面可以放大缩小.

 

Splitter.h 中定义的类 Splitter 继承自 Ctrl 类. 

class Splitter : public Ctrl {

}

 

Splitter.h 位于 U++Framework/upp/uppsrc/CtrlLib 目录.

而 Ctrl 类的声明见 U++Framework/upp/uppsrc/CtrlCore/CtrlCore.h

Ctrl 类的具体实现见 U++Framework/upp/uppsrc/CtrlCore/Ctrl.cpp
