Describe the bug

in the begging it's ok , but after change blue part (a vbox), the green part becomes weird

this code seperate the whole into left & right and stick right to most right
`func (z MiddleRenderer) Layout(size fyne.Size) {
// / 剩余空间全给市场部分 */
// z.marketPanel.Resize(fyne.Size{
// Width: size.Width - z.ctrlPanel.Size().Width,
// Height: z.marketPanel.Size().Height,
// })
// //z.marketPanel.Move(fyne.Position{X: 0, Y: 0})

// /* 仓位部分靠近底部 */
// z.posiPanel.Resize(fyne.Size{
// 	Width:  size.Width - z.ctrlPanel.Size().Width,
// 	Height: z.posiPanel.Size().Height,
// })
// //z.posiPanel.Move(fyne.Position{X: 0, Y: size.Height - z.posiPanel.Size().Height})

/* 行情 + 仓位 */
/* VSPLIT PART */
tickPanelSize := fyne.Size{
	Width:  size.Width - z.ctrlPanel.Size().Width,
	Height: size.Height,
}
z.tickPanel.Resize(tickPanelSize)
z.tickPanel.minSize = tickPanelSize

/* 控制区域 */
/* STICK TO RIGHT */
z.ctrlPanel.Move(fyne.Position{X: gapp.fyneWindow.Content().Size().Width - z.ctrlPanel.Size().Width, Y: 0})

// z.container.Refresh()

}`

but after change the positions vbox, things get weird
`{
// middleSize := z.middlePanel.Size()
z.positionsList.RemoveAll()
for _, bpos := range w.Positions {
for _, pos := range bpos {
if pos == nil || pos.Qty <= 0 {
continue
}
log.Printf("ui new pos entry")
entry := newPostionEntry()
entry.Coin = pos.TradePair
entry.OpenPrice = pos.OpenPrice
entry.Qty = pos.Qty
entry.Profit = .0 // todo
entry.Direct = pos.Direct
z.positionsList.Add(entry)
}
}
// z.middlePanel.Move(fyne.Position{X:0, Y:0})
// z.middlePanel.UpdateSize(middleSize)
// z.middlePanel.Show()

}`

You should remove all of those Max containers, they do nothing (a Max with 1 item is the same as not using a container at all, widgets will always fill the space available.

Instead of all your manual code I would use container.NewBorder(nil, nil, nil, right, content), so that the right component takes up space on the right and content fills the remaining space.
