I would like to add Command's to a View's pulldown-menu (the triangle-shaped button in the upper right corner that the "Problems"-View in Eclipse also has).
Can anyone point me in the right direction how to do this declaratively in plugin.xml?
I found a tutorial that used a viewContribution (extension point org.eclipse.ui.viewActions), but unfortunately using this extension point i can only add Action's to this menu.
The functionality i wish is actually quite similar to the Problems-View (Showing Compiler-Errors and -Warnings in Eclipse):
I want to filter records within my View according to an Entry chosen in the pulldown-menu of the View.
For an example configuration you can use the implementation of the Problem View itself. It uses the org.eclipse.ui.menus extension point to contribute that menuItem through a dynamic contributor. You can check the details in the plugin.xml of the org.eclipse.ui.ide plugin. Look for the usage of the class org.eclipse.ui.internal.views.markers.FiltersContribution. In its "getContributionItems()" method it returns menu contributions dynamically each time the menu is to appear. Of course, doing it this way is not exactly declarative. For that try reading the guide at http://help.eclipse.org/indigo/topic/org.eclipse.platform.doc.isv/guide/workbench_cmd_menus.htm (you should use your command instead of the global ones, of course)
Hope it helps!

Does Xcode have a way to show the caller function of a method? I want to know all of the calling functions of a method in a class. A solution would be to find the method in the project, but sometimes different classes have methods with the same name - That could find us a method we're not looking for..
Many other IDEs have this capability, such as Visual C++ 2003/2005/2008,Eclipse ...
Can you do this in XCode?
Xcode 4.4 intrudced this functionality:
New Features in Xcode 4.4 (Scroll down to 'Find and Search Additions')
Move your cursor on top of the function you are interested in
Open the Assistant editor(⌃ +⌘+Enter)
On the top of the assistant editor, Select 'Callers'
You will see a list of all the function that's calling your function
Not the as effective as other IDEs, but does the job.
Yes. Set a breakpoint inside your method, then when it breaks, there are two spots to see a stack. First is in Xcode's "console" area (usually the bottom middle), there is a top-bar which may not immediately appear to be navigable, but it is a select-style UI control which has the entire stack in it. Selecting a different level shows you that scope's variables, etc. and pops your editor to that exact file (where you can mouse-over variables to see their in-memory real-time values). Second is in the left-hand area (where you normally browse files). There is another tab there (besides the file browser) for exactly this purpose. There is a slider at the bottom which controls how many "steps" in the stack you see; clicking on one has a similar affect.
For simple refactoring such as method re-naming, you can use the contextual-menu when you right-click a selected method-name, and Xcode will replace all identical selectors in your project. However, this does not address what you mentioned about different classes having methods with the same signature. It does, however, give you a very nice interface for reviewing the changes in-context and easily accepting or rejecting them one at a time.
It might be noted, however, that changing method signatures often may be a sign of poor design, and particularly if you have to do it with methods which have the same signature on different classes (which are not "siblings" and therefore should both get the rename)
How did they do it? Look at these images:
As you can see you can slide the right panel to the left and back. Is that UISplitViewController?
That's definitely a custom view/controller. The stock split view is what it is. Although I think Matt Gammell cooked up a replacement split view that let's you drag the split around, it only changes the proportional size or visibility of your two views. It would take some additional customization to give it this kind of look and feel. I don't have the URL handy though, I'm sorry.
I don't know if you still need this, but you can check this open source class called IIViewDeckController available in github - it's exactly what you need. You can set a right and a left view, add shadows, customize tap or slide interactivity.
It contains a example project so you can understand how to program all properties.
I'm relatively new to Cocoa and I would like to implement the ability to add or delete items from a pop-up menu in the same way that the OS X System Preferences/Network Location pop-up works. Selecting the 'Edit Locations...' option rolls down a window that provides the ability to add to, or delete from the existing Location list. My interest in doing things this way is as much about conforming to the relevant Human Interface Guidelines as having a way to dynamically change the menu content. (I have no real problem with the 'background' coding side of things, it's the user interface that's my primary issue at this stage.)
Is this a standard IB View?
On the surface, I can't see anything appropriate, but maybe that's just my inexperience. I'm assuming that, because this is not an uncommon sort of requirement, the task should be pretty straightforward and that Apple, or someone, would even have a relevant code sample to show how to define such a window.
Can anyone point me in the right direction?
Sorry for the late answer. I found this tutorial: http://cocoadevcentral.com/articles/000014.php
Does anyone have an example of using a QWidget as an editor in a QAbstractTableModel?
I have a column which when edited should create a QCombobox with the list of choices.
The docs seem to suggest I need to write a QAbstractItemDelegate and a custom paint function but that seems overkill to simply pop-up a standard QCombobox in Qt::EditRole.
Note - the combo box contents are the same for every row and it only needs to be shown when somebody clicks in the cell.
I know this should be simple but I can't get it to work. It's easy for a QTableWidget based table - but I need it for a very large data table.
The docs seem to suggest I need to write a QAbstractItemDelegate and a custom paint function but that seems overkill to simply pop-up a standard QCombobox in Qt::EditRole.
You don't need to go that far. One way is to subclass QStyledItemDelegate and then override createEditor() so that it returns your prepopulated combo box. Its setEditorData and setModelData functions will probably already suffice if you`re using basic Qt value types.
If you need something more generic that works across many different models, you can create a QItemEditorFactory that associates your editor with the correct type. This also works well with custom types.
When indicated by your view's EditTrigger, your view will get the delegate specific to the cell on which the edit is being invoked and call delegate->createEditor(...) which can then size the combo box according to the options parameter as well as set the current entry to the value specified by the model, although most of this should be handled by the QStyledItemDelegate. Thus, you won't have to worry about the Qt::EditRole directly as the view will handle that.
Did you try and have a look at the following example from Qt :
Spin Box Delegate Example
Maybe it will give you a much clearer view on the subject !
Hope it helps a bit !
I'm trying to create a very simple selection list widget based on NSOutlineView. However, I'm having a hard time figuring out how to display an icon and a label right next to it, which is really the expected behavior in all the mainstream implementations of that kind of widget out there (iTunes, mail, Finder,...).
So far I am just binding two separate cells, but then when I'm expanding the tree, the icon cell grows larger and a gap appears between the icon and its accompanying label. I know I can probably overcome this problem by extending NSCell and provide a custom class, but as what I'm trying to achieve is really the standard thing, I can't be resigned to accept that there isn't a simpler solution.

Sadly, there isn't a 'text and icon' cell that you can just use, fresh out of the box as you would like. However, when I was working on a project, I found that Apple released some sample code that implements this, since it is such a common idiom.
This can be found here, specifically ImageAndTextCell.h/m
It can help teach you about UI customization by reading through this example, but scratching that, just dropping the ImageAndTextCell straight into your project should do just fine.
You need to create ImageAndTextcell to combine text and icon..
you can create ImageAndTextcell like this Sample Project
