Re: [Gambas-user] gb3: using array of structures with dimensions unknown until runtime

2012-07-04 Thread Emil Lenngren
When you are declaring the array by writing
A[3] As Single
you declare an inline array, i.e. NOT a reference to an array.
So you cannot write
ThatStruct.A = AnArray.
Instead you have to copy the contents from AnArray into A.

  Dim Normals As New Tile_Normals[TileGrid.Size, TileGrid.Size]
 
  When I try to assign a value to an array element like this:
 
  Normals[TileGridX, TileGridY].A = Convert.Normal(P1, P2, P3)
 
  I get a null object error. While the 2D array of structures seems to
  be created correctly, all its initial values are indeed null. Do I
  need to create the structure or array differently so I can properly
  assign values to it?
 
  Previously I knew all the dimensions of my arrays of structures so they
  were statically defined, but in this case I don't know the array
  dimensions until after the program has started running. Thanks everyone.
 

 One addition. I've discovered that if I publicly declare a 2D array of
 the structure it shows bad number of dimensions and out of bounds
 errors when I double-click it after creation:

 ' Tile grid normal structure.
 Public Struct Tile_Normals
A As Single[]  ' Normal for quad subsurface A.
B As Single[]  ' Normal for quad subsurface B.
 End Struct
 Public Normals[32, 32] As Struct Tile_Normals

 Declaring it as a 1D array it behaves normally:

 ' Tile grid normal structure.
 Public Struct Tile_Normals
A As Single[]  ' Normal for quad subsurface A.
B As Single[]  ' Normal for quad subsurface B.
 End Struct
 Public Normals[32] As Struct Tile_Normals

 It also doesn't make any difference if I define the structure like this:

 ' Tile grid normal structure.
 Public Struct Tile_Normals
A[3] As Single  ' Normal for quad subsurface A.
B[3] As Single  ' Normal for quad subsurface B.
 End Struct

 Maybe that's related to what's happening, or a separate issue?

http://code.google.com/p/gambas/issues/detail?id=265

Unless I am mistaken, gb.desktop relies on xdg-utils to report the desktop  
currently in use. The more I dig into this the more it looks like the  
problem is more with xdg-utils not properly reporting Mate as the active  
desktop.

As a temporary workaround, if it were possible to expose the desktop.type  
property as read/write, the property could be set to GNOME which should  
force the system to use the gnome keyring system for saving passwords.

The importance in this is that Mate has a growing number of users as a lot  
of users do not like the direction of Gnome3 nor KDE. Mate is a  
continuation of the Gnome2 look and feel.

I will continue to look at how xdg-utils can be made to detect Mate.

http://code.google.com/p/gambas/issues/detail?id=263

There is a problem with GTK+, that sometimes uses an X11 window for drawing  
controls (like TextBox), and sometimes does not.

Consequently, if you send a TextBox to the background, you will continue to  
see it (or part of it).

I don't know what you want to achieve exactly. Please give more details,  
and I may be able to tell you what to do to workaround that problem.

As for the CheckBox, please provide more details : a screenshot for  
example. The better of course being a project that allows me to reproduce  
the problem on my computer!

Comment #7 on issue 268 by emil.len...@gmail.com: Can call non-static  
_unknown from a static context
http://code.google.com/p/gambas/issues/detail?id=268

Some more things:
* What should happen if _property is static but _unknown is dynamic or vice  
versa? ;) This code:

Static Public Function _property() As Boolean
End

Public Sub _unknown(...)
End

Public Sub TestFunction()
   Me.uuh = 3
End

- Segmentation fault (The gambas stack gets corrupted)

And

Static Public Function _property() As Boolean
   Print This is not written to stdout
End

Public Sub _unknown(...)
   Print This is written to stdout
End

Public Sub TestFunction()
   Me.uuh()
End

- i.e. _property is silently ignored, but _unknown is executed.

* _property must also be checked in about the same way when a property is  
written to:
Static Public Function _property() As Boolean
   Print This message will not be written to stdout.
   Return True
End

Static Public Sub _unknown(...)
   Print Not this message either
End

Public Sub TestFunction()
   Me.uuh = 3
End

- Shows nothing on the screen, i.e. none of _property or _unknown are  
executed, and no error message.

* In revision #4894 you cannot call a static function when having an  
object, like obj.unknown_function(), err msg static function. But the  
convension is that static functions can actually be called even if you have  
an object. obj.known_static_function() works.

As Benoît says,
Dim Normals As New Tile_Normals[TileGrid.Size, TileGrid.Size]
only gives an array where you can store references to Tile_Normals.

You also have to do:
Dim I As Integer
Dim J As Integer
For I = 0 To TileGrid.Size - 1
  For J = 0 To TileGrid.Size - 1
Normals[I, J] = New Tile_Normals
  Next
Next

Otherwise you will get null object errors.

Re: [Gambas-user] Issue 268 in gambas: Can call non-static _unknown from a static context

2012-07-04 Thread gambas

Comment #10 on issue 268 by emil.len...@gmail.com: Can call non-static  
_unknown from a static context
http://code.google.com/p/gambas/issues/detail?id=268

Now some more headache :)

Public Function _property() As Boolean
   Return False
End

Public Function _unknown(...) As String
   Return hello
End

Public Sub TestFunction()
   Print Me.uuh()
End

- Wanted Stream, got String, i.e. stack is corrupted.

And as you say, static unknown method called in dynamic context does not  
work yet, like it should by convention...

[Gambas-user] ScrollView and Hovered property

2012-07-04 Thread Adrien Prokopowicz
Hi,
I noticed that, when entering into a ScrollView, the Hovered property is
always false :

Public Sub ScrollView1_Enter()

  Debug Last.Hovered

End

Public Sub ScrollView1_Leave()

  Debug Last.Hovered

End

... will make :

FMain.ScrollView1_Enter.14: False
FMain.ScrollView1_Leave.20: False

in any way. I haven't tried yet with other controls.
Here is a little test project if you want.

Regards,
Adrien.

By the way, Kevin, did you try the jit compiler for your game?
