Hej!
Statements about grid layout...
1. It does not seem to be possible to stop filling the whole cell width
of a column for an added text field. It means that all widgets in the
same column in a grid layout will all have the same width. No auto
parameter only a fixed static size.
Sorry, I have problems to understand what you mean.
2. No layout widgets are today possible to adjust themselves with sizes
and positions according to the parent's changes of sizes.
Again, what do you mean?
3. The setWidth method for individual widgets put in a grid layout does
not have any effect at all.
It depends on the value of allowStretchX and allowStretchY.
Are all statements above true? Is this the intention? How is it then
thought to solve the normal way of creating an advanced form where you
do not want absolute positioning or absolute sizes? By using multiples
of horizontal and vertical boxes? That would be a less beneficial way.
Absolute positioning is not an alternative.
Why is the grid layout connected with setColumnWidth and setRowHeight,
when a better way would be to adjust itself after the widgets sizes in
the grid, at least as an alternative? Is there a performance limitation?
HTML table limitation? or is it just a design issue?
The main reason is because we haven't already implemented it. The grid
was just build for the listview. We should invest some more time in the
grid itself. Auto-sizing for a grid is also not that easy. Especially if
you also want to support row- and col-spans. Also auto-sizing mean a
performance impact I think.
I must say that if it is like I have stated above, I do not really like
the design of the grid layout. There seem to be very big limitations for
creating an advanced form with relative sizes and positions of widgets,
and relative parent resizing and positioning.
The most things are possible. Maybe you don't like that it's not yet
completely done. This is a good base to contribute I think ;)
