1、概述
源码放在文章末尾

该项目实现了多种样式的导航按钮控件

• 1. 可设置文字的左侧、右侧、顶部、底部间隔。
• 2. 可设置文字对齐方式。
• 3. 可设置显示倒三角、倒三角边长、倒三角位置、倒三角颜色。
• 4. 可设置显示图标、图标间隔、图标尺寸、正常状态图标、悬停状态图标、选中状态图标。
• 5. 可设置显示边框线条、线条宽度、线条间隔、线条位置、线条颜色。
• 6. 可设置正常背景颜色、悬停背景颜色、选中背景颜色。
• 7. 可设置正常文字颜色、悬停文字颜色、选中文字颜色。
• 8. 可设置背景颜色为画刷颜色。

下面是demo演示：

项目部分代码如下：

#ifndef NAVBUTTON_H
#define NAVBUTTON_H/*** 导航按钮控件 * 1. 可设置文字的左侧、右侧、顶部、底部间隔。* 2. 可设置文字对齐方式。* 3. 可设置显示倒三角、倒三角边长、倒三角位置、倒三角颜色。* 4. 可设置显示图标、图标间隔、图标尺寸、正常状态图标、悬停状态图标、选中状态图标。* 5. 可设置显示边框线条、线条宽度、线条间隔、线条位置、线条颜色。* 6. 可设置正常背景颜色、悬停背景颜色、选中背景颜色。* 7. 可设置正常文字颜色、悬停文字颜色、选中文字颜色。* 8. 可设置背景颜色为画刷颜色。*/#include <QPushButton>#ifdef quc
