SDL2SpecialCharacterMapping problem

Hi Alvaro,

This is not an area I've been involved in, but just a general comment...

Can you export a self contained example from your code that can be loaded

into a fresh Image that demonstrate the problem?

Its always easier if people can see the problem with their own eyes.

Also, what version OS/VM/Image are you running?

i.e. World Menu > System > System Reporter

Hi,

Iam having a problem handling some OSKeywordEvents. These events should have character associated.

The mapping is resolved by SDL2SpecialCharacterMapping using a dictionary(Mappings), it has the mapping, for example, for left arrow and right arrow.

It resolve correctly for "left arrow" with key: 1073741904(Integer) , but it does not found "right arrow" with key: 1073741903(Integer).

Both keys are present.

Any idea?

In fact, I have the answer.

But I’m afk, I will answer later, sorry :)

Hi Ben,

The thing is that i found that the problem can be reproduced without my code.

​

The class has a class variable named "Mappings" (photo shows an inspector of it).

There are associations for left and right arrow:

                                - (1073741904 -> arrowLeft)

                                - (1073741903 -> arrowRight)

If i send  "Mappings at: 1073741904" i get "arrowLeft",

but if i send "Mappings at: 1073741903" i get "nil" instead of "arrowRight".

This is done automatically when handling OS events, but as this fails i am not getting associated character for "arrowRight".

Just in case i send you the information you requested.

Thanks

Hi again, 

well, the problem is that 64bit images are translated from a 32bit version and some particular dictionaries need to be rehashed. 

1073741904 is a long integer in 32bit and a small integer in 64bit ;)

If you execute this: 

SDL2Structure allSubclassesDo: #compileFields.

OSWindowMorphicEventHandler initialize.

SDL2SpecialCharacterMapping initialize.

and you will be ok :)

Of course, right fix would be to rehash dictionaries when converting. 

and right-right fix would be to bootstrap also 64bit version instead bootstrap 32bit and then translate. 

but since just a few people uses SDL2 right now, the problem arose recently (in fact, I realised it recently, when I was doing some experiments).

cheers!
