\brief The QwtDynGridLayout class lays out widgets in a grid, |
|
adjusting the number of columns and rows to the current size. |
|
|
|
QwtDynGridLayout takes the space it gets, divides it up into rows and |
|
columns, and puts each of the widgets it manages into the correct cell(s). |
|
It lays out as many number of columns as possible (limited by maxColumns()). |
