我一直在研究我的 UI，所有这些东西都编译得很好，但我也编写了我的大部分代码，然后为它生成了头文件。但是这个头文件不会编译——没有错误。它根本不在构建目录中。

墨水.h

#ifndef INK_H
#define INK_H

#include <QPaintDevice>

namespace Ui {
class Ink;
}

class Ink : public QPaintDevice
{

public:
    explicit Ink(QWidget *parent = 0);
    ~Ink();

private:
    Ui::Ink *ui;
};

#endif // INK_H

墨水.cpp

#include "ink.h"

#include <QtCore>
#include <QtGui>
#include <QWidget>
#include <QPainter>
#include <QPaintEvent>

void ink()
{


    QFile *brushInput; //takes raw 8 bit grayscale image, 8 bit values only
    char *brushProto;
    uchar *brushData;


    brushInput = new QFile("x:\\Development\\InkPuppet\\brush.raw"); //open the raw file
    brushInput->open(QIODevice::ReadOnly);
    QDataStream in;
    in.setDevice(brushInput);
    int size = brushInput->size(); //set size to length of raw file

    brushProto = new char[size];
    in.readRawData(brushProto, size); //read file into prototype
    brushData = new uchar[size];

    for(int i = 0; i < size; ++i)
    {
        brushData[i] = (uchar)brushProto[i]; //copy char to uchar array
    }

    QImage test(brushData, 128, 128, QImage::Format_Indexed8);
    QImage test2(128, 128, QImage::Format_ARGB32);

    QVector<QRgb> vectorColors(256); //create color table
    for(int c = 0; c < 256; c++)
    {
        vectorColors[c] = qRgb(c, c, c);
    }

    test.setColorTable(vectorColors);

    for(int iX = 0; iX < 100; ++iX)
    {
        for(int iY = 0; iY < 100; ++iY)
        {
            test2.setPixel(iX, iY, qRgba(255 - (qrand() % 100), 0 + (qrand() % 100), 0 + (qrand() % 100), qAbs((int)test.pixel(iX, iY)-255)));
        }
    }

    //final conversion for stencil and color brush
    QPixmap testPixmap = QPixmap::fromImage(test2);
    QPixmap testPixmap2 = QPixmap::fromImage(test);

    QPainter painter(this);

    painter.drawPixmap(150, 50, 100, 100, testPixmap);
    painter.drawPixmap(50, 50, 100, 100, testPixmap2);

    delete[] brushProto;
    delete[] brushData;
    delete brushInput;
}

主文件

#include "inkpuppet.h"
#include "ink.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    InkPuppet w;
    w.show();

    return a.exec();
}

在 QT creator 中创建新表单时，必须选择 Qt Designer Form Class 才能生成相应的 .cpp 和 .h 文件，否则只会生成 .ui。
