Conditional placement (1 Viewer)

[Rob Hexenmeister]

Good evening,

Can anyone please tell me what is wrong with the following syntax:

<posX>#(iif(eq(#facadeview.layout,"list"),1282,0))</posX>

Many thanks

Not 100% sure, the wiki is unreachable for me right now to verify. Does the <posX>#(iif(facadeview.list,1282,0))</posX> work?

I did a quick search in my local skin files. For what it's worth, this property is being used inside many, many of the <visible>-Elements of all skins I have installed. By contrast I could only find 2 occurences of the #facadeview.layout-Property in all my local files.

Thank you for the idea, but no, it doesn't. In fact xpos doesn't seem to like any expressions at all, only integers.

I have just checked DWHD and my own "Clarity" skin, and there is not a single instance of posX or posY containing expressions. I have a vague recollection that expressions are supported only for specific tags, and posX/posY are not included in that set.

I think that you will need to duplicate the entire control (with different values for posX), and then use the visible tag to select one or the other.

Thank you, yes that is my conclusion too, but it won't work as it is Control id 2 on the video shares screen that I wanted to conditionally place, and I can't duplicate the ids.

Things I have tried:
Duplicating the control with the same ID and using the visible tag - won't work because of duplicate ID
Using slide to move the control - won't work because the focus doesn't move with the slid position and stays in the original x,y location
Using the expressions
Trying to use a define.

Looks like I am stuck with it unless anyone has a solution.

Many thanks.

it is Control id 2 on the video shares screen that I wanted to conditionally place

Is this the file "MyVideos.xml"? Control id 2 seems to be the "View as" button that in "DWHD" and "Clarity" appears inside the group that forms the left side menu. What effect are you trying to achieve?

• "View as" button always on screen, but in different positions, according to the current facade.
• "View as" button appears and disappears as part of a menu, but the menu has different positions according to the facade.

The only possibility that occurs to me at the moment is to create two small files each containing control id 2, with the different X positions, and then use the include tag to include each file with a condition that tests the current facade value. So when the facade is "list", file A is included; when the facade is not "list", file B is included. However...

To work properly, it would require the skin engine to re-interpret "MyVideos.xml" when the facade value is changed, and I don't know whether it does that.

Good evening,

Yes, exactly that one.
Principally, effect one is the most important, placing the menu controls according to the current facade.

That is an interesting idea, using the include tag. I don't know either, whether the page is reloaded on facade change. I would have to try that out.

You have got me thinking though that another possibility, if the skin does not reload on facade change, might be to send the focus to another screen (very briefly) on changing the facade:

on the videos.xml
#(skin.setfocus(35,999)


on another screen (in this example window id 35)
<id>999</id>
<onfocus>#(skin.setfocus(2,50)</onfocus>

But the question would be how to trigger the first #(skin.setfocus(35,999)) on the videos.xml window. I wouldn't want to do it every time focus is lost from control id<2> and if I put the setfocus command in <on click> that might stop the actual purpose of the control changing the facade from working.

Definitely some things to experiment with. Thank you for your input.
