— 本帖被 XChinux 执行加亮操作(2016-04-10) —

用于生成LED屏幕显示的数组，学习了一些控件的用法，了解了Qt的界面框架。




- 软件开源
- vs2013+qt5.6.0
- 自定义LED屏幕像素尺寸
- 只用于灰度LED屏幕
- 支持旋转，翻转等操作
- 鼠标中键可以拖动，滚轮缩放大小
- 可以保存成GAQ文件，方便下次接着编辑
- 可以导入图片，成生图片数组（二值化方式）
- 右键导出数组txt
- 支持文字输入
- 支持中文和英文

vs2013支持c++11，程序里面的nullptr  lamda表达式这些都要c++才行，你的mingw 的时候要加一个参数，-std=c++11

jx347638458:刘大师您编译成功了么,我的有很多错误 (2016-04-10 14:27) 

稍做修改，就可以了。如果用QtCreator打开，需要在pro中加CONFIG += c++11
要把qtextctrl.h qtextctrl.cpp两个文件加到工程中，加到GridArrayQt.pri文件中也可以
HEADERS += ./GridArrayQt.h \
    ./QDrawArea.h \
    ./common.h \
    ./qtextctrl.h
SOURCES += ./QDrawArea.cpp \
    ./GridArrayQt.cpp \
    ./main.cpp \
    ./qtextctrl.cpp
QDrawArea类的setPointCursor改成如下形式
void setPointCursor(const QPointCursor & pc, const QCursor &c)
QTextCtrl类的第二个构造函数改成
QTextCtrl(const QRect &rect, QWidget *parent = 0)
应该就可以了。
如果有必要，所有代码文件编码改成UTF8
