<div dir="ltr"><div>Hi!</div><div><br></div><div><div>I'm developing a Dash to run mainly in XFCE, but can run on others too. </div><div>I'm trying to reserve space in the display area so that other applications do not occupy the same place in which it is the Dash, as the bar kde or unity ubuntu tasks. </div>
<div>The code developed is running, but is not reserving the space, if I maximinimizo another application it is underneath the Dash and not to limit it. </div><div><br></div><div>I would like your help to understand what is wrong or what is missing in the code. The Dash should be on the left side of the screen with the full height of the screen, with 230 prixels wide and is called just before the widget->show ():<br>
