Subject: [PATCH] fix: After adjusting the width of the dde-file-manager, other
 applications such as file editors open dde-file-dailog field display

Adjust the adaptive width strategy, and when the window width is less than the width of all columns, adjust the columns larger than the minimum width. When the window width is greater than the width of all columns, adjust the width of the filename column

Log: After adjusting the width of the dde-file-manager, other applications such as file editors open dde-file-dailog field display
