按类别列出问题

1. [TheIDE] 在工程 Calculator 中添加某一目录下的文件.

Posted by haifeng on 2023-06-27 17:43:38 last update 2024-08-07 14:46:09 | Answers (0) | 收藏

在左下角点击右键, insert special-->Import directory tree into package

由于使用了 std::string_view, 所以编译前更改一些选项. 如果是 VS2019, 则在 C/C++ --> 语言, C++语言标准中选择 ISO C++17标准(/std:c++17)

如果使用的是 U++,

在 Build methods 中, Builder: MSC19

Common C++ options: /std:c++17

但此时可能会带来一个错误 C2872, "byte": 不明确的符号

原因是是 C++17 定义了 std::byte 类型, 而 Windows 也定义了 byte 类型. 如果使用 using namespace std; 则会导致冲突, 编译器不知道采用哪个定义.

若使用 Visual Studio, 则解决的办法可以是加入命令行参数 /D_HAS_STD_BYTE=0

2. UPP 中获取系统变量的一些函数

Posted by haifeng on 2023-01-14 14:44:53 last update 2023-01-14 14:44:53 | Answers (0) | 收藏

Cout() << "Home directory: " << GetHomeDirectory() <<"\n";

Cout() << "Programs Folder: " << GetProgramsFolder() <<"\n";

Cout() << "Programs Folder(X86): " << GetProgramsFolderX86() <<"\n";

Cout() << "Temp directory: " << GetTempDirectory() <<"\n";

更改目录

ChangeCurrentDirectory("D:\\bin");

3. [UPP] help 中的 .tpp 文件如何转换成 .tppi 文件?

Posted by haifeng on 2022-08-21 07:59:25 last update 2022-08-21 07:59:25 | Answers (0) | 收藏

例如文件 main_en-us.tppi 的内容如下

TITLE("This is Topic++ example page")
COMPRESSED
120,156,139,86,80,81,49,208,49,80,54,32,0,172,92,82,211,18,75,115,74,98,163,171,227,107,85,93,253,116,67,131,21,162,139,13,172,109,21,162,181,204,20,66,50,50,139,21,128,40,36,191,32,51,57,65,59,65,91,33,181,34,49,183,32,39,85,161,32,49,61,53,86,45,22,164,84,1,74,193,20,39,42,68,199,149,128,53,88,37,232,39,232,67,244,234,39,22,20,36,232,131,116,25,37,168,164,230,37,232,150,22,199,41,228,100,230,101,43,148,228,43,36,230,229,151,100,164,22,65,12,213,131,26,23,27,11,0,207,59,59,34,

这里 COMPRESSED 部分的内容是如何获得的?

4. 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.

5. 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()

6. Upp 的 core.h 中重复加载 math.h

7. Upp 中的一些函数简介

Posted by haifeng on 2021-04-11 09:18:51 last update 2021-04-11 10:21:59 | Answers (0) | 收藏

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
