I'm starting with developing on Windows phone 8.1. I've been working with the different image assets for logos and tiles, but have not been able to identify the one that is displayed when you go to the list of open apps (i.e. pressing and holding the back key). In this view there is a logo of the app in the bottom-left corner that I don't know from where it comes. I'm trying to change the background color of it, but is none of the ones define in the manifest. I've seen apps that have this image with a specific background color (i.e. not transparent) like the one in the screenshot below. So, there must be a way to do it, but I'm not able to find where or how.
That would be the application icon you set in your WMAppManifest.xml. You can find this under your project's Properties folder. You can set icon from the UI (App icon) or by editing the XML block itself.
<IconPath IsRelative="true" IsResource="false">Assets\ApplicationIcon.png</IconPath>
This is the same icon that is shown in phone's app list. If image has transparency, phone's selected accent color is shown as "background". If not, well.. then it won't be transparent :).

In my Qt5 app, I wanted to display a tiny icon in the title bar. I used
setWindowIcon(QIcon(":/icons/Mylogo.png"));
To my surprise, the icon appears (on my Ubuntu) on the sidebar, along with the other active tasks, but not in the title of the window. With the messages from my app, I also reveive
QPixmap::scaled: Pixmap is a null pixmap
that may be the reason why I do not have the icon. Do I make something wrong, or do need to do something extra? (i.e. the pixmap exists, found, and used on one purpose, I guess)
No minimum example and no info about window manager.. my advice is to look into platform notes for Setting the Application Icon
Your icon may be under control of e.g. KDE/GNOME theme.
I'm writing a codenameone application where I want to have an image displayed across the top of the screen as a header. I do not want to include this image in every form/container that I create so therefore I came up with the following solution:
I have a Main form which contains the image (North) and a container (Center) which will then hold all the components of the specific screen that I want to show.
I will then create containers that represent each individual screen. My idea was to add these containers to the container of the main form, one by one and that navigation between them would be handled by changing the contents of that main screen container.
But I cannot find out how to make this work. As long as I have one single screen to show it is easy... The main form container can be an embedded container that is set to show the container for the single screen. But when I try to navigate to another I cannot make it work.
So, is there another approach I should use?
If not, how should I handle navigation between screens?
Is this with a GUI builder app or with a handcoded app?
Either way a simple way of customizing this if your app has a side menu or Toolbar would be to customize the TitleArea UIID to include your background image. E.g. start with a modern theme like the Business Theme and in the designer theme change the title area border property to be "Empty".
Then define the background image to be the image you want with "scaled to fit" or "aligned bottom" depending on what you want. Make sure to include enough space in the image for the title are and use a multi image so it will adapt for other OS's.
How do I get the new toolbar item style of OSX Yosemite?
I created a standard toolbar, but the buttons don't have that button-like look. Do I need to drag actual buttons to the toolbar to get this look?
What I have:
What I want (that round bezel and white background):
There are two types of items in toolbars, image items and view items. It looks like you have an image item. You seem to want a view item where the view is an NSButton configured as a round textured button. So, yes, you should drag actual buttons to the toolbar.
I would not attempt to control the button background. You should use the button as-is to get the default system appearance. Apple recommends using a PDF template image (all black with the alpha channel used to make the image). The button itself would not have a title/label. Rather that would be on the containing toolbar item.
It looks like you may have applied an internal blue "glow" or highlight to your image. Generally, you should not do that. Let the frameworks apply appropriate effects to the template image automatically based on the button state and shows-state-by mode.

Works just fine for my Cocoa app under Yosemite -
are you actually setting the template property for your icon images..?
From the NSImage docs:
The 'template' property is metadata that allows clients to be smarter
about image processing. An image should be marked as a template if it
is basic glpyh-like black and white art that is intended to be
processed into derived images for use on screen.
I'm using this template TileWide310x150PeekImage03 from the documentation here. On the example image, the name of the App is not displayed on the image, but on my App the name of the app remains.
This ruins the UI of my tile because the App name is displayed within the image of my flipping live tile. How do I remove it?
Add branding="none" to the binding element in the template XML.

From the Mac OS X HIG:
As with the icons that can be used inside toolbar controls, the system applies various effects to sidebar icons. To help you understand how these effects can change the appearance of a sidebar icon, consider the Finder Home icon, shown here in its unprocessed state[...]
So I'm trying to get my NSOutlineView to render a black sidebar icon with the typical new Lion style. I'm using a view-based NSOutlineView. However, I'm unable to find anything in the docs and if I simple set the imageView.image property to the sidebar image, it renders in black. So I figure there must be some sort of opt-in mechanism to get the sidebar to render it properly. Any suggestions on how to achieve that?
Apart from using the setTemplate: method of NSImage, you can just rename your images. This is from the documentation of imageNamed:…
If an application is linked in Mac OS X v10.5 or later, images
requested using this method and whose name ends in the word “Template”
are automatically marked as template images.
