ScrollableView - manually position the PagingControl

Hey there!

It would be great if we could position the PagingControl freely within the ScrollableView.

What I am trying to do is putting the paging control INSIDE the ScrollableView because at the moment I have placed the ScrollableView at the very bottom of the screen and you can barely see those dots.

  • iphone
  • pagingcontrol
  • position
  • scrollableview
  • I have the same problem - seems like I can't get them to be totally visible in the view. Looks like they are half in, half off the bottom of the screen. Appcelerator?

  • I have the same question? Can I position the controls inside the view? I'm trying to create a fullscreen scrollable view…

  • Hi, this function isn't implemented in Titanium, but you can easy fix that.

    I used a transparent paging in my project to see the dots over my images.

    To make this:

    Open /Library/Application Support/Titanium/mobilesdk/osx/1.x.x/iphone/Classes/TiUIScrollableView.m (where 1.x.x is your version of sdk, like 1.4.2, 1.4.3 or 1.5.0)

    find this line in this file:

    viewBounds.size.height = visibleBounds.size.height - (showPageControl ? pageControlHeight : 0);

    and change to this:

    viewBounds.size.height = visibleBounds.size.height; // - (showPageControl ? pageControlHeight : 0);

    now, find this:

    contentBounds.size.height = viewBounds.size.height-(showPageControl ? pageControlHeight : 0);

    and change to this:

    contentBounds.size.height = viewBounds.size.height; //-(showPageControl ? pageControlHeight : 0);

    for optional i put in my code a option to contro the opacity of this bar:

    find this:

        [[self pagecontrol] setBackgroundColor:[[TiUtils colorValue:args] _color]];

    and paste this code before:

        [[self pagecontrol] setAlpha:[TiUtils floatValue:opacity]];

    Save, and make a full compile of your project.

    now to use:

    yourScrollable.pagingControlColor = 'YourColor';
    yourScrollable.pagingControlOpacity = YourOpacity;

    YourColor can be in these formats: 'transparent', 'black' or '#ff00ff'
    and YourOpacity can be: 0 (transparent) to 1 (opaque) or like this: 0.75 (75% of opacity)

    • Great. Thanks a lot. In 1.7.0RC the problem continues…

    • Works great in SDK 1.7.0 - thanks for the step by step too.

    • would it be possible to change only the background color to transparent and leave the dots opaque? When I add your changes the dots disappear too.

    • just saw that you mentioned that I can use "transparent" as a color! That fixed it! sorry

    • Is this implemented in the core now (SDK 2.1.1)?

      — commented August 21st 2012 by Daniel Krusenstråhle
    • works like a charm :)

    • This is really cool and should be in the standard SDK !

  • bump

    Another question: 'pagingControlColor' controls the background color of the pagingControl.
    Can we change the color of the dots?

    • Did anybody manage to figure out if you can change the color of the dots?
