Re: Changes in -performSelectorOnMainThread: from iOS 6 to 7?

2014-02-14 Thread Rick Mann 
performSlectorOnMainThread still exists. Although I'm re-writing my app from 
the ground up, I'm posting an interim release which will continue to use this 
approach. The behaviors between the OSes are different, and I was looking for 
some indication as to why.

Re: Display selectd sub-menuItem in NSPopUpButton

2014-02-14 Thread Leonardo 
Hi John,
Thank you for the code. I suppose I missed something because it doesn¹t work
as expected.
I did:

I created a popUpMenu on IB and put it on the window and connected to the
outlet popUpButton.
I connected the popUp outlet to the delegate¹s action popUpButtonAction.

I created a menu with a single menuItem anc connected to ³selectionMenu².
I created a menu with menuitems and submenus and connected it to
³flyOutMenu².

What did I forget?

When I select a submenu item, the popUP menu marks its sate as YES but it
doesn¹t display it on the closed popUp.
When I re-click on the popUp, the only one item selected is the one under
the mouse.

Anyway, I succeeded as I explained on my previous email to the list.
I click on a smple button and build a NSPopUpButtonCell and pop it up with
performClickWithFrame:
I use an NSTextField to show the latest selected item¹s title.
I would like to re-click and pre-select that meu item but I didn¹t succeed
yet.


Regards
-- Leonardo

I would be highly surprised if using that method would not be considered use of 
private API. The two public init methods are useful when you want to create 
pages yourself. When opening a PDF document you’ll have to resort to other 
options to perform custom setup of pages. Is there a particular reason that you 
really need to be active during the init process? I find that I can do whatever 
I need by iterating through a document’s pages shortly after loading the 
document. You could declare a method on your subclass, say “finishSetup”, and 
then call that on each page as you iterate throughout the pages once you have 
obtained the document from initWithURL:.

Given that the new concurrency method goes back a couple of years (iOS 5), 
surely your interest in how the old way works is academic?

Re: Display selectd sub-menuItem in NSPopUpButton

2014-02-14 Thread Leonardo 
Thank you Keary.
In the meantime I dismissed that NSPopUpButton and put a simple button + a
NSTextField aside. They look as a group.
When I click on the button I create on the fly a NSPopUpButtonCell and pop
it up with performClickWithFrame:
Then when the user selects a menu item, the menu item invokes its
target-action and I get the menuItem tag and title then I put that title
within the NSTextField. I release the NSPopUpButtonCell. Done.

The thing I have still to do is: when the user pops up the menu, I should
select and display the latest selected menuItem, opening all of its parents'
menu. And I don't know how to do that. Do you have an idea?

The purpose is: I have a short hierarchical tree of objects, and the user
should be able to choose an object quickly, without opening other panels.

I basic problem is that NSPopupButton does not support submenus. You can get 
the submenu item title to appear when the menu is dismissed but the side effect 
is that the item will be added to the top menu. I didn't go any further with 
that approach. It is too bad, because I would argue that there are good use 
cases for hierarchical menus in popup buttons.

I don't have any real solutions, however, although I can suggest that you could 
"hide" the side effect with a "recents" section of the menu. Otherwise you will 
have to subclass NSPopupButtonCell and take over title and menu handling, 
AFAICT.

PDFPage init methods not called

2014-02-14 Thread jonat...@mugginsoft.com 
PDFPage has two declared initialiser methods:

- init
- InitWithImage:(NSImage *)image

When creating a PDFDocument with -initWithURL: neither of the above are called 
on my PDFPage subclass.

A bit of digging reveals that what is called is the undocumented:

- (id)initWithPageRef:(id)pageRef

This seems peculiar. Will defining an override on -initWithPageRef: count as 
the use of private API?

I suspect that this is just an oversight in the header.

OpenCL Basic Programming Question

2014-02-14 Thread Gerriet M. Denkmann 
I am trying to build the Basic Programming Sample in: 


I have myKernel.cl:

__kernel void squareq(  __global float* input, __global float* output )
{
int i = get_global_id(0);
printf("i %d\n",i); //  never seen
output[i] = input[i] * input[i];
}  

and myKernel.cl.h:

void squareq_kernel( cl_ndrange *range, float* input,  float* output);

main.c has:

#define NUM_VALUES 999 
size_t bufferSize = sizeof(cl_float) * NUM_VALUES; 
float* test_in = (float*)malloc( bufferSize ); 
for( NSUInteger i = 0; i < NUM_VALUES; i++ ) test_in[i] = i;
cl_float *mem_in = gcl_malloc( bufferSize, test_in, CL_MEM_READ_ONLY | 
CL_MEM_COPY_HOST_PTR ); 
cl_float *mem_out = gcl_malloc( bufferSize, NULL, CL_MEM_WRITE_ONLY );  
dispatch_sync(queue, ^void
{
cl_ndrange range =  {   1,
{0, 0, 0},  
 
{NUM_VALUES, 0, 
0}, 
{0, 0, 0}   
 
};  
squareq_kernel( &range, mem_in, mem_out );   <- 
EXC_BAD_ACCESS (code=2, address=0x13228)
}
);

Builds without warnings, but crashes when run (see above).

What am I doing wrong?

Gerriet.

Display selectd sub-menuItem in NSPopUpButton

2014-02-14 Thread Leonardo 
I have filled my NSPopUpButton with menu and submenus.

When I select a menuItem on the root menu (so, not a sub-menuItem), it
propery displays the menuItem selected. And when I re-click on the popUp
button, I get the selected menuItem under the mouse.

But if I select a sub-menuItem, it doesn't display it. And if I re-click on
the popUp button, I don't get it under the mouse. Any time I click on the
button, I have to look for the selected item diving in the menu hierarchy.

Any solution?

NSPDFPanel accessory view validation

2014-02-14 Thread jonat...@mugginsoft.com 
NSPDFPanel can display an accessory view.

Is there any way to validate the accessory view input prior to closing the 
panel?

In my case the user can can specify that a password should be required when 
opening the resultant PDF.
I want to prevent the panel closing when the password requirement has been 
specified but the password has not been supplied.
