Ugh! I am having trouble visualizing sizers. Here's what I want to see:

vertically: 4 rows

row1: panel(top) , then Hsizer , then topbutton01 + (horizontally) topbutton02

row2: wxScrolledWindow , then Vsizer , then 6-rows by 8-cols of 8buttons

row3: panel(mid) , then Hsizer , then midbutton01 + (horizontally) midbutton02

row4: wsRichTextCtrl

I can't figure out what I am doing wrong. -Thanks! ...V

Ok, I got it somewhat (see below), but I can't seem to get row-1 and row-3 to be the size I want it. So I'll mess with set_size. Ideally, What I want is
row-1 height = 50
row-2 height = 200
row-3 hekght = 50
row-4 height = 200

Any tips will be greatly app...

I have been working for 12hrs straight on this crazy thing.
I have made some headway, not with set_size (see code), not with setting size in CREATE either.
Setting Width seems to work. But Height of Controls doesn't want to work.

The only luck i have with setting Height is in add_window_to_sizer. If I use ALIGN , specifically, wx_or_all(wxALIGN_LEFT & wxALIGN_TOP). Then I can get topbutton01 and topbutton02 to park at TOP, but wxALIGN_LEFT & wxALIGN_RIGHT , don't do anything.

Also,
set_size( panl, 500,500 )
set_size( panltop, -1, 20 )
set_size( topbutton01, 200, 20 )
don't seem to work at all.
I didn't try to ALIGN midbutton01 & 02 , just to show the diff between using ALIGN and not using it.
I could sure use some expertise on my ALIGNment of Controls.
Thanks! ...V

I think the problem is that you're passing a 1 for the third parameter (option) when adding everything. If you don't want the item to grow when the sizer does, pass 0.

OK, by changing to:
add_window_to_sizer( panlbox, panltop, 0, wxGROW, 0 )
add_window_to_sizer( panlbox, scrollwin, 1, wxGROW, 0 )
add_window_to_sizer( panlbox, panlmid, 0, wxGROW, 0 )

panltop and panlmid HEIGHT work fine. NO luck yet with ALIGN_LEFT or ALIGN-LEFT. AND I still can't control the height of scrollwin.
If scrollwin is ,,0 then I loose topbuttons and midbuttons visability.


Either way, if I manually stretch/change(hold down left mousebtn and drag edge of form) the form vertically, top and mid buttons disappear. Their panels are still there, but buttons are gone.
However, when I manually stretch/change the form horizontally, left or right, the buttons re-appear. There's that problem.


Then there's this: I can control the height of txted. But scrollwin remains incorrigible, can't yet change its height.
Stranger than fiction.
Thanks! ...V

btw: What's the best way to visualize sizers:
A sizer controls the THING(control) that sits directly on top of the sizer. Is this correct?

I mostly think of them like rubber bands that get stretched.

Yes, I see what you mean by 'like rubberbands'.
I have never seen a diagram of Sizers.
And I am trying to get an accurate visual of Sizers and how they fit together with other controls.
So, if I liken controls to a stack pancakes,
with wxFrame as the bottom pancake, and say the red pancakes are sizers and the non-red ones are other controls.
What I'd like to get confirmation on, is the positional characteristics of a sizer.
Ie., A sizer controls the THING(control) that sits directly on top of it, (Add_window_to_sizer).
And a sizer itself, sets upon the THING (control) that it is working for, as in (set_sizer)command.
So my friend, is my visual accurate. Or have I gotten it wrong?
Thanks! ...V

BTW: I have made some headway on my (guess I could say 'our') pgm.
The main prob was with these two statements:
add_sizer_to_sizer( panlbox, panlboxt, 1, wx_or_all(wxALIGN_LEFT & wxALIGN_TOP), 0 )
add_sizer_to_sizer( panlbox, panlboxm, 1, wx_or_all(wxALIGN_LEFT & wxALIGN_TOP), 0 )
Not sure why, but they cause the pgm to go Krazy.


Anyways, most things are solved, except for Positioning top & mid buttons.
What I want to do is put button 1&3 on left side, and button 2&4 on right side of parent panel.
Any tips are greatly appr...

BTW: I have made some headway on my (guess I could say 'our') pgm.
The main prob was with these two statements:
add_sizer_to_sizer( panlbox, panlboxt, 1, wx_or_all(wxALIGN_LEFT & wxALIGN_TOP), 0 )
add_sizer_to_sizer( panlbox, panlboxm, 1, wx_or_all(wxALIGN_LEFT & wxALIGN_TOP), 0 )
Not sure why, but they cause the pgm to go Krazy.


Anyways, most things are solved, except for Positioning top & mid buttons.
What I want to do is put button 1&3 on left side, and button 2&4 on right side of parent panel.
Any tips are greatly appr...
Thanks! ...V

You need to use space_sizer() to have blank space take up any slack between the buttons: 

  --[this Window sets upon this SIZER]     
  add_window_to_sizer( panlboxt, topbutton01, 0, wxSHAPED, 0 )  
  space_sizer( panlboxt, 0, 0, 1, wxGROW, 0 ) 
  add_window_to_sizer( panlboxt, topbutton02, 0, wxSHAPED, 0 )    
 
  add_window_to_sizer( panlboxm, midbutton01, 0, wxGROW, 0 )     
  space_sizer( panlboxm, 0, 0, 1, wxGROW, 0 ) 
  add_window_to_sizer( panlboxm, midbutton02, 0, wxGROW, 0 )

Yes, I see what you mean by 'like rubberbands'.
I have never seen a diagram of Sizers.
And I am trying to get an accurate visual of Sizers and how they fit together with other controls.
So, if I liken controls to a stack pancakes,
with wxFrame as the bottom pancake, and say the red pancakes are sizers and the non-red ones are other controls.
What I'd like to get confirmation on, is the positional characteristics of a sizer.
Ie., A sizer controls the THING(control) that sits directly on top of it, (Add_window_to_sizer).
And a sizer itself, sets upon the THING (control) that it is working for, as in (set_sizer)command.
So my friend, is my visual accurate. Or have I gotten it wrong?

Yep, that's correct. A sizer makes sure that everything inside of the sizer (sizers and other controls) change their size and position when the 'parent' of the sizer changes its size or shape.

Ah yes, 'rubberbands and pancakes'. Sounds like a Disney movie.

Thanks for that definition Matt. That helps a great deal; I have given up my 'pancakes' in favor of your rubberband 'inside of', a rubberband frame inside of a parent frame. Nice to have a verbal to go along with a visual.
Thanks! ...V .

Ugh! I thought I had mastered sizers and off to my next challenge, FONTs.

But not quite, I am hung up on making horizontal unstretchable.
Why would we want the Buttons to be unstretchable?
I would want the Buttons to stretch Horizontaly, if I dragged the Frame Horizontally.
Can someone explain this? Thanks! ...V

Just put 1 in place of the 0 where it says "make horizontally unstretchable".

What exactly are you trying to do with fonts?

Most buttons do not stretch. For instance, the Preview and Post buttons here on the forum. I usually put buttons into sizers for positioning. It's only for things like edit areas that I want to stretch.

FONTs:
I plan to use fonts 1stly for an array of Buttons, 

-- eucode 
atom tempbtn       
for i = 1 to 6 do       
	for j = 1 to 8 do    
	    tempbtn = create( wxButton, {scrollwin, -1, sprintf("Button %dx%d", i & j), 0, 0, 90, 60} )       
	    add_window_to_sizer( button_grid, tempbtn, 1, wxGROW, 0 )      
	end for --j     
end for --i


and secondly, for :
txted = create( wxRichTextCtrl, {panl, -1, "Enter Text Here", -1, -1, 399, 250} )


In wxEuphoria, will we eventually move toward txted.font.style type of format.?
Thanks! ...Vern

-- In wxEuphoria:  
txted  = create( wxRichTextCtrl, {panl, -1, "Enter Text Here", -1, -1, 399, 250} )

In Delphi/pascal, a similar RichEdit Control definition looks lik this: 

  object txted: TRichEdit 
    Left = 14     -- These are properties of object txted: TRichEdit 
    Top = 296 
    Width = 675

    Font.Color = 41972491 
    Font.Height = -13

  begin         
    txtInFileName := OpenDialog1.FileName; 
    FileNameLabel.Caption := txtInFileName; 
    txted.Lines.CLEAR; 
    txted.Lines.LoadFromFile(txtInFileName); -- Load txted with text 
    txted.Visible := True; 
    PrepWordsCount(txted); 
--      SaveAsDialog.FileName := txtInFileName;       ForceCurrentDirecotry 
  end 
  else txtInFileName := ' '; 
end;


The problem I have with Delphi/Pascal is that their executables are very Large. Tripple true for Pascal crossplatform. Guess I am old-school.

What you're describing is dot notation, an inherent feature of object-oriented programming. Euphoria is not object-oriented, and does not have that form of syntax. Similar features can be had with Euphoria's namespace feature, which I believe Matt is planning to add into wxEuphoria for the next major release. (Though I could be wrong on that.)

Here's an example of how I understand it would work... 

// wxWidgets C++ code 
#include <wx/frame.h> 
 
wxFrame * frame = new wxFrame( parent, id, title, pos, size, style ); 
wxToolBar * toolbar = frame->CreateToolBar( style ); 



-- wxEuphoria code
include wxFrame.e as wxFrame 
 
atom frame = wxFrame:Create( parent, id, title, pos, size, style ) 
atom toolbar = wxFrame:CreateToolBar( frame, style );


As you can see, such methods would make for almost line-to-line conversion of C wxWidgets programs.
