Creating a Toolbar with Drawer Menu in CAD ObjectARX

Implement creating a toolbar in CAD and adding menu commands, as shown below:


Reference article: > [cad --- menu, toolbar, screen menu, enhanced toolbar](https://blog.csdn.net/zeqi1991/article/details/102810373)

The main implementation path is to create a dockable window, creating toolbuttons within it, adding commands to the button click events, and displaying the submenu at the button position. For smoother interaction, you need to override the menu style.
As mentioned in the article, you can control controls via an XML file, which can omit the steps of modifying interaction.
I only implemented a simple horizontal layout and cancelled the button border background here. I also need to add adaptive modification content so that both top and side docking can be achieved.
There isn’t much to say about the code logic, so I’ll put the code directly below:
