| # Easy QR code generator | ||
| - if you testing | ||
| - if you need easy generate | ||
| # QR code generator | ||
|
|
||
| Simple app for QR code generation. If you need testing, saved or packet generation QR codes. (Tested on windows 10/11 and Qt 5.12.11) | ||
|
|
||
| 1. Build library golang | ||
| ### Notes: | ||
|
|
||
| Use build args: | ||
| For build app with GUI use Qt (install first and check ENV qmake and mingw32-make). For correct build Not use '-j16' | ||
|
|
||
| -o qrcode.dll -buildmode=c-shared | ||
| ```sh | ||
| $ mingw32-make clean -j16 & qmake & mingw32-make | ||
| ``` | ||
|
|
||
| 2. Build binary file with Qt | ||
| For building DLL ('go_src' folder): | ||
|
|
||
| src in "Qt src" | ||
|
|
||
| (for example, folder "files" include dll) | ||
| ```sh | ||
| go build -o qrcode.dll -buildmode=c-shared -ldflags "-s -w" | ||
| ``` | ||
|
|
||
| For using DLL on windows use | ||
|
|
||
| - Save file: | ||
|
|
||
| ```sh | ||
| RUNDLL32 qrcode.dll, Rundll32save "test example" 1 testName.png | ||
| ``` | ||
|
|
||
| - Copy to clipboard: | ||
|
|
||
| ```sh | ||
| RUNDLL32 qrcode.dll, Rundll32ToClipboard "test example" 3 | ||
| ``` | ||
|
|
