So basically, I have a react app and I am trying to create a grid of square elements but:
i dont want to
shrink them below a certain size (meaning that when the page
shrinks, the last elements on a row are pushed to the next row
etc.).
I was also hoping to put in a few special 2x2 elements in the grid (realistically not
many, between 1-3)
I am looking to be able input a series of objects (ordered by priority) and have the page dynamically allocate them into the grid space as best it can.
I have done bootstrap grids in the past, 1. could be achieved fairly easily by changing the .col-x value at certain screen widths so the elements wrap
But 2. seems really hard:
making a static row with a 2x2 element and some 1x1 elements seems
easy, but then it will all break when the above row tries to wrap, or
when i have to wrap elements in this static row.
I was also thinking of offsetting 2 consecutive rows and just placing a div with the 2x2 boxes over the offset, but then i would have to change the row elements that are being offset on the fly, and i dont know how to get an element to tell me what row and column it is in.
Any ideas?

The problem is I have two columns that will be filled with rows that are implicitly defined, and that I DO NOT want to resize the adjacent row items such that there is a space beside the components. I have tried using grid, but the result is the second image. Similarly, I use flexbox, and the row space emerges implicitly. Does anyone know a way to get this kind of 'dense' packing as in the first image?
I have a grid inside a component which has some rows and columns. The problem is that there is some empty space after the last row of the grid and I want to get rid of it. This is what it looks like in the inspector, it actually shows that the whole content is the grid, whereas only the rows with actual information are the content of the grid. I want to remove this white space which is there for no reason. For clarification this is the empty unwanted space:
You could use setHeightByRows to set the Grid to contain a fixed amount of rows, or setHeightUndefined to always show all the rows (bad idea if your Grid ever has massive amounts of data in it).
I have an object with keys and values that I want to represent in a responsive way so that are always next to each other, but two k/v entries are stacked because of overflow on the horizontal direction, they will be aligned like a table.
Here is an example of what I am trying to accomplish:
This looks close to what I want, but does not account for the content size. max-content does not work
This also touches on it but recommends flex instead, but flex rows are all calculated independently so that rules that out.
I have a series of buttons that I want to appear in columns at the bottom of my QML page. The number of columns across should depend on the width of the window, as the window width increases I want more columns to be added. (And fewer rows as a result as components are pulled up to the previous line)
This is sort of like a Flow component, but I want the items to appear in columns, evenly spaced across the page, in rows and columns (columns centered vertically, at the bottom of the page). Sort of like GridLayout.
I can't figure out what QML component(s) to use to achieve this.
I think what you're looking for is a GridView. See the layout documentation.
I'm not positive, but based on your description I think you would just need to set the flow property to GridView.FlowTopToBottom.
I am using ItemTemplate ( that is ViewCell ). I got know about the Orientation article in Xamarin documentation but there is no point about handling ListView orientation.
Hope to get the answer

As you can see from your screenshots, this is not an orientation problem, your listview IS the full width in both cases, what is quite possibly wrong are your layout options.
Can you show us your item template definition?
You are using a grid inside the ViewCell?
In that case, first make sure the grid's horizontal options are set to FillAndExpand, then check the grid column size definition.
Can you also show us the grid's column size definitions?
If they all have fixed sizes assigned, then they will always be that size, no matter how much unsued space there is.
There are 2 ways to make them use more space.
If possible, you should use the "star" sizes. This is where you give your columns sizes as portions of the available space.
If you give your first column the size 1*
and the second column size 1*
they will both take exactly half of the available width.
You can use any other numbers to select portions, such as three columns with sizes 5* 3* 1*
Which would make your first column 5 times as big as the third, and the second column would be 3 times as big as the third.
Again, in total, they will take the entire available width.
The second column sizing option is to use "Auto" sized columns, which will size the columns according to the elements inside them. Whatever size the largest element inside that column (in any of the rows) takes, that is the size that column will have.
To take the whole screen width in this case, at least one of the columns content should have "AndExpand" on it's horizontal options.
This is somewhat easier as it will automatically size the columns and you just take care of populating them properly with content, but be wary as this approach is significantly slower.
Finally, if you experience performance issues, consider implementing the ViewCell with an AbsoluteLayout. It can be a bit more pain to set up, but should work faster than grid if you have a bunch of rows inside the list view and a bunch of data in each row.
