pb窗体中数据窗口大小调整或自适应最大化，函数resize()

// 获取调整后整个窗体新的尺寸
tab_1.Height = newheight
tab_1.Width = newWidth
// 设置数据窗口dw_1的宽度及位置 - “左侧距离窗体” - “右侧距离窗体”
tab_1.tabpage_1.dw_1.width = tab_1.tabpage_1.width - tab_1.tabpage_1.dw_1.x  * 2

tab_1.tabpage_1.dw_4.height = tab_1.tabpage_1.height - tab_1.tabpage_1.dw_1.height - tab_1.tabpage_1.dw_1.y * 2
tab_1.tabpage_1.dw_4.width = tab_1.tabpage_1.width - tab_1.tabpage_1.dw_4.x*2

tab_1.tabpage_2.dw_2.height = tab_1.tabpage_2.height - tab_1.tabpage_2.dw_2.y*2
tab_1.tabpage_2.dw_2.width = tab_1.tabpage_2.width - tab_1.tabpage_2.dw_2.x*2
