    I have already answered this 3 times. I said you need a stretch after the grid layout, assuming I understand what you want. I can't say it any more.

    @JonB, what is a stretch? I don't see it in the side bar, under which group should I find that?

    Kind Regards,

      I don't run Designer but it's there on the toolbar. Horizontal & vertical stretchers. They look like blue stretches when you place them. They should end up generating

      vertLayout.addStretch()
      

      I think/assume. void QBoxLayout::addStretch(int stretch = 0).

        Spacers not stretch :)
        Stretch is the stretch factor to stretch a layout item over multiple layout "slots"

          I have written what I thought it was. I thought spacers were fixed size. Anyway whichever you say! It's some blue thing in Designer :) The link I gave for addStretch() states:

          Adds a stretchable space (a QSpacerItem) with zero minimum size and stretch factor stretch to the end of this box layout.

          Isn't that it?

            @JonB I'm running version 5.9.2 of Qt Designer, there is no stretchers...Spacers there is thank you @Pl45m4 , but I don't want to spacer things out stretch is the correct terminology just don't see it.

            I have now modified the source adding a call to:

            mpui->pvtloMain->addStretch(1);
            

            Ok, now with this its different, the whilespace between the QHBoxLayout layout and QGridLayout is now gone and when resizing the grid layout moves with the window, unlike before when it stayed anchored to the bottom, however its still not right because its not "stretching" the content, instead is moves up the window with space under the layout not occupied.

            Just to be absolutely clear I don't want space, I want the content of the QGridLayout to resize as the container is dragged. In the same way it already does when dragging out horizontally.

            Kind Regards,
            Sy

              I had no idea that was what you wanted. That's why I asked each time.

              So I think you need to set the grid layout (as a whole, not an individual row) to occupy as much height as possible. Now is that what you want?

                  Dunno, I just play till I get what I want :) At least we finally seem to be agreeing about what that is!

                  Don't you have to set the grid in the vertical layout to expand its height as much as possible?

                  Is QBoxLayout::addLayout(QLayout *layout, int stretch = 0) what is wanted? With a non-0 stretch.

                  Otherwise maybe @Pl45m4 can state what is wanted here?

                        @JonB The QGridLayout is added to the QVBoxLayout in the designer, I cannot set the layoutRowStretch property, trying to set it to 1, it goes right back to 0 after I press enter.

                          My last attempt, because I'm going out, and someone who knows designer better than me can doubtless say.

                          The stretch needs to be set on the layout items added to the enclosing vboxlayout. That (the vboxlayout) has stretch factors doesn't it, or not? Temporarily put a stretch of 1 for its first first item, the hbox, and a stretch of 100 for its second item, the gridlayout? That's probably not fully right but does it do what you want? Else I don't know which way to do it.

                            did you set max height of the Gridlayout ? or the sizepolicy to fixed ?

                                @JonB, the QVboxLayout has the property layoutStretch with I've changed from 0,0 to 1,100.

                                Thats the puzzle solved! It works perfectly, thank you for your help and support.
