cl.arkui.3 Change in <SideBarContainer> Component Attributes and Display Modes

Added the minContentWidth attribute, whose default value is 360vp. If this attribute is not set, the value 0vp is used. If this attribute is set to a value less than 0, the default value is used. In Embed mode, when the component size is increased, only the content area is enlarged; when the component size is decreased, the content area is shrunk until its width reaches the value defined by minContentWidth, and then the sidebar is shrunk until its width reaches the value defined by minSideBarWidth; if the component size is further decreased, while respecting the minimum width of the sidebar, the content area is further shrunk, with the content clipped, until it is 0 vp large. minContentWidth, whether it is specified or kept at the default value, takes precedence over minSideBarWidth and sideBarWidth of the sidebar.
Changed the default value of minSideBarWidth and SideBarWidth to 200vp in API version 9 and earlier versions, and 240vp in API version 10.
Added the Auto display mode. The sidebar is displayed in Embed mode when the component size is greater than or equal to the sum of minSideBarWidth and minContentWidth and in Overlay mode otherwise. If minSideBarWidth or minContentWidth is not set, the default value will be used for calculation. If the calculation result is less than 600 vp, 600 vp will be used as the breakpoint value for mode switching.
