I have a nested layout 4-levels of nesting as in the attached photo
- top layout is MainHorLayout |
-
|--QVBoxLayout_______________ Hosts CheckBoxes |--AllfigVlayout_____________ Hosts figures |-TopHlayoutfig_0_1_______Hosts profile_0,Profile_1 charts, downside labels | | | |-- TopVlayoutFig_0_Lbl (loaded with chart[0], chart[0].belowlabel) | | | |-- TopVlayoutFig_1_Lbl (loaded with chart[1], chart[1].belowlabel) | |-BotHlayoutfig_2_3_______same as TopHlayoutfig_0_1 but for bottom fig 2,3 | |-- TopVlayoutFig_2_Lbl (loaded with chart[2], chart[2].belowlabel) | |-- TopVlayoutFig_3_Lbl (loaded with chart[2], chart[2].belowlabel)
I'm using check box to toggle the charts[i] visibale/ unvisible start up behaviour is shown in phot 1 No problem with Charts[0] and charts2 as in photo 2
The problem when i'm trying to hid charts1 it hides charts[0] and 1 also trying to hide charts3 it hides both 2 and 3 please check photo 3
when i trying to show them again the dimensions of charts is not equall and non symetrical please check photo 4 as it shows when program starts
