从头开始创建一个图形库

尝试做一个完整的窗口。就像一个Windows表格。你可以在没有动态的情况下做到这一点，但既然你已经部分实现了，我想你会得到一个类似Windows的 "橡胶 "窗口。

最难的部分将是画纽扣:))

是的，我想这是最难的部分，因为没有任何。))))。

卷轴是单独制作的，它们可以应用于特定的窗口配置，其余的（事件、对所需属性的改变）将自动完成。连接它们是非常简单的。

   _scroll_v.Create(_main,_grid_cols,true,30);
   _scroll_h.Create(_main,_grid_cols,false,30);

关于创建表格的难度：引擎的结果非常好，所以用它创建一个表格并不难。

谢谢你为我的显示器提供的演示。

就这样。

最初实施的是 "橡胶 "窗口机制。

但在调整大小的时候。

窗户不应该闪烁。
应该有8个用于调整大小的窗口把手--每边和每个角落都有。

事实上，窗口作为一个实体并没有形成。目前还没有诚信。

根据想法，你应该来一个类似的选择。

嗯，总的来说，你肯定做得很好!我没有想到。))))

继续前进。

Maxim Kuznetsov 2020.10.14 12:09 #138

我想起来了!

我想起了这一切让我想起了什么......。

GVision（TVision的后代之一）的演示。

在大约93-95年，你可以在列宁斯基街的 "科技书屋 "书店买到上述的演示（*谁不知道--软件是以零售方式出售的）。
甚至还有一个单独的显示器，上面滚动着演示，你可以 "尝试"。它很酷--标志、按钮、检查/广播框和图形......。

但后来我买了一辆Zortec-C。一个沉重的盒子，里面有5卷文件和一些软盘：-)

好记性。

继续。

1.大量使用矩形和坎肩的动态，如果所有东西都在一个坎肩上，也许不会眨眼，平台已经有了限制，在一个坎肩上画所有东西是不可取的。也许如果只是为了在DirectX上一次性翻译...

2.我刚刚添加了一个小组件，实现了拉伸。而且没有完整性，只是组装的元素，也不一定是图形。

你没有想到什么？伸展？这对我来说就是这么简单。我为我的项目制作这些东西，我没有计划创建图形控件库，尽管创建的基础非常好。

Aliaksandr Hryshyn:

1. 矩形和坎肩在动态中被大量使用，如果所有东西都在一个坎肩上，也许它不会眨眼，但已经有平台的限制，在一个坎肩上画所有东西是不可取的。也许如果只是为了在DirectX上一次性翻译...

2.我刚刚添加了一个小组件，实现了拉伸。而且没有完整性，只是组装的元素，也不一定是图形。

你没有想到什么？伸展？这对我来说就是这么简单。

它的闪烁是因为你改变了整个画布的尺寸，这很耗费资源，但如果你在最大尺寸的画布上改变可见图像的区域，你就能摆脱这种不愉快的效果。也就是说，你事先创建一个显示器屏幕大小的kanvas，将图像连接到它（同样大小），然后 "裁剪 "它。而调整大小的功能只会定义画布的可见区域，而不是重新创建它。

从头开始创建一个图形库 - 页 14
