Info window; deselect all

Hi,

I am getting started in scripting with blender, I want to know how to deselect all selected lines in the info window, as I am often copying and pasting from it, sometimes i forget to deselect old lines of py script.

Ohh, sorry its just hotkey “A”.

row = layout.row()          row.operator("mesh.select_all", text="select/unselect", icon='') 

maybe this help

the icon argument can’t be empty, either leave it out (=no icon) or give it an icon string. If you need a placeholder in the size of an icon, use ‘BLANK1’

yeess!! sorry my mistake!
even you can delet the “icon” part

row.operator("mesh.select_all", text="select/unselect")
