Problem with GLOBAL var

[arfgh]

Hey there.

i defined this global variable to be used in my Base forms:

Code: Select all

Global FrameSize as new com.sun.star.awt.Size

For some reason that i dont know, the values in 'FrameSize.width' and 'FrameSize.height' are erased and the value change to 0 each time i navigate to the next record. And i defined it as GLOBAL, so then i dont understand which is the problem. I have tried also to define it in other module, with the same bad result.

please help.

thx in advance

I believe each time the macro runs anything already stored in FrameSize gets wiped out the next time the macro runs because you are assigning it “ as new com.sun.star.awt.Size “
Try simply declaring it with

Code: Select all

Global FrameSize

and then assigning it a value inside the sub/function.

can you please be more deep ?
because i tried a lot of diferent declarations with the same result.

Here is an example based on Listing 253 from Andrew Pitonyak's book "OpenOffice.org Macros Explained". with added lines
"Global FrameSize" and
"if i = 0 then
FrameSize = vFrames(i).getComponentWindow().getSize()
endif"

Code: Select all

REM  *****  BASIC  *****

Global FrameSize

Sub QueryFrames
Dim vFrames As Variant 'All of the frames
Dim vFrame As Variant 'A single frame
Dim i As Integer 'Index to enumerate the frames
Dim s As String 'Contains the string to print

REM Call the queryFrames() method on the XFrames interface.
REM This takes one argument, a FrameSearchFlag.
REM This searches the children of the desktop.
vFrames = StarDesktop.getFrames().queryFrames(com.sun.star.frame.FrameSearchFlag.CHILDREN)

For i = LBound(vFrames) To UBound(vFrames) ' The return value is an array.
s = s & vFrames(i).Title & CHR$(10) ' Append the title and a new line.
  if i = 0 then
    FrameSize = vFrames(i).getComponentWindow().getSize()
  endif
Next
 
MsgBox s, 0, "Frame Titles" ' Display the titles.
End Sub

Using the IDE set a Watch on FrameSize and run the macro once. It will store the size of the first frame it finds in Global FrameSize.
Again in the IDE single step into the beginning of the macro and in the Watch window you can expand FrameSize where you can see that the stored values persist from the previous run of the macro.

but UnklDonald418, i always use the 'Option Explicit'. And in that example.. Global FrameSize, isnt defined its type.

[UnklDonald418]

Define it as Variant, which is the default type assigned by Star Basic.
