PB DW内容自适应-鸿蒙开发者社区

思路

1、记录上一次DW大小、名称等信息。
2、根据DW最新大小除以上一次记录的DW大小,计算出缩放比列。
3、循环出DW中字段、控件等、根据类型分别计算出长宽高、X、Y坐标等。

源码

1、创建Custom Class对象、命名为uo_dwresize
2、使用

uo_dwresize dwresize
//open事件中
//实例化
dwresize = create uo_dwresize
//记录初始DW大小
dwresize.of_add_dwsize(dw_1)

//根据特定需求增加自适应方法
//根据DW大小,内容自适应
dwresize.of_draw_dwsize()

3、源码

forward
global type uo_dwresize from nonvisualobject
end type
type str_dwsize from structure within uo_dwresize
end type
end forward

global type str_dwsize from structure
	string	ls_classname
	long		ll_width
	long		ll_height
	datawindow		ldw_datawindow
end type

global type uo_dwresize from nonvisualobject
end type
global uo_dwresize uo_dwresize
