Layout2d documentation:

Layout2d - a mechanism that allows you to arrange widgets, as well as its size dynamically, depending on external variables. Each Widget contains Layout2d. If you want to operate widgets as before, just do not set a value for it; if you have already set it, just apply layout2d = Layout2D.NullLayout; In Layout2d, you set a condition for different widget values, such as position and size. Any condition begins with this.N =, where N is the value that we will calculate.

The following external variables are available for use:

This widget:

• "this.h" or "this.height" - get current widget height.
• "this.w" or "this.width" - get current widget width.
• "this.X" or "this.left" or "this.l" - get current widget left.
• "this.Y" or "this.top" or "this.t" - get current widget top.

Window variables:

• "W.h" or "W.height" - get window height.
• "W.w" or "W.width" -get window width.

Parrent variables:

• "&.w" or "&.width" - get parent width.
• "&.h" or "&.height" - get parent height.
• "&.X" or "&.l" or "&.left" - get parent left.
• "&.Y" or "&.t" or "&.top" - get parent top.

You can also get the value of the widget by its ID:

• "[id].w" or "[id].width" - get [id].width.
• "[id].h" or "[id].height" - get [id].height.
• "[id].X" or "[id].l" or "&.left" - get [id].left.
• "[id].Y" or "[id].t" or "&.top" - get [id].top.

Expression example: "this.X=W.w/3;this.Y=W.h*0.5"
