Dear Luciano Vieira,<br>
<br>
The first problem you describe is a genuine bug wrt updating check
controls and radio controls. It does not occur with any of the other
controls. Fortunately, there is a workaround: if you wrap the
control in a so-called layout control, then positioning and
refreshing works fine (I must confess that I find that rather odd).
Don't forget to include zero margins in the layout-control
attributes. So, change the radio control and check control to::<br>
<br>
<tt> :+: LayoutControl (RadioControl
[("botão1",Nothing,id),<br>
("botão2",Nothing,id),<br>
("botão3",Nothing,id)] <br>
(Rows 1) 3 []) [ControlPos
(LeftBottom,zero),ControlHMargin 0 0,ControlVMargin 0 0]<br>
<br>
:+: LayoutControl (CheckControl
[("botão1",Nothing,NoMark,id),<br>
("botão2",Nothing,Mark,id),<br>
("botão3",Nothing,NoMark,id)] <br>
(Columns 3) []) [ControlPos
(RightBottom,zero),ControlHMargin 0 0,ControlVMargin 0 0] <br>
</tt><br>
I've tested this with SDI and MDI windows, and it works on my
machine.<br>
<br>
The second problem you describe is actually not a bug, but correct,
yet admittedly unexpected, behavior. You write: <br>
"When we minimize the window and maximize it again, the interface
looses the background"<br>
This suggests that you think that once you have drawn an image on
the window canvas, it should remain there. However, this is not true
in Object I/O. In Object I/O, the look function is responsible **all
the time** for rendering the entire, correct content of the window
(or control). The behaviour that you describe follows from that: <br>
<ol>
<li>you create a window with a look function that displays a red
bitmap image. If you resize this window, it will constantly
display this image</li>
<li>if you press the button 'Write a Text!' then its callback
function lookText is evaluated. Its effect is that it first
draws the second bitmap and changes the look function of the
window. The effect of the latter operation is that after that
moment, all refresh requests will be handled by the function
writeLookText</li>
<li>now suppose you resize the window or cause any other reason to
refresh part of the window, the function writeLookText redraws
the content: it **only** draws the text "Refresh refresh " in
black using font Arial in bold style and point size 20. In
particular, it does not redraw the background. So that should be
done first.</li>
</ol>
You can get the desired behavior by:<br>
<ol>
<li>removing the first line of the lookText function (so the line
that draws the bitmap in the window)</li>
<li>add the following line immediately before setting the pen
colour to black in writeLookText:</li>
</ol>
<tt> # picture = drawAt {x=0,y=0} bitmapFundo2 picture</tt><br>
<br>
I suppose that you wish to use non-monochrome bitmaps in a later
stage. If not, it is much more efficient to either set the pen
colour (setPenColour) with the appropriate colour and fill a
rectangle of the proper size or set the pen background colour
(setPenBack) and unfill a rectangle of the proper size.<br>
<br>
Hope this helps,<br>
Regards,<br>
Peter<br>
