Open Screen / Open Font
 

Hi,

I am trying to clone the Workbench-Screen. Therefore I need to set up a TextAttr-Structure to open the Screen's Font for myself. My question is, if I must store that TextAttr-Structure and the fontname in it until I close the font or if I can free both after I have the font opened?

I have read this: http://amigadev.elowar.com/read/ADCD.../node05B2.html
but it is still not clear to me.

EDIT: I am now using the tag "Sa_SysFont" (set to 1) to say that I want to have the WB's font in my screen. No need to do any further font stuff. ;)

Not directly answering your question, but if you're running on Kickstart 3.0 or later, you can use the SA_LikeWorkbench tag when opening the screen instead.

If you want to clone the default public screen (which is usually Workbench, but might not be) use LockPubScreen(0) instead of LockPubScreen("Workbench").
Generally, I think you may as well also pass SA_MinimizeISG when opening a custom screen too.

Well, I followed your tip. Everything is well, except the icons have all the wrong colors.

Maybe try using SA_FullPalette when you open the screen? Or set the palette manually with SA_Colors?

From the OpenScreen autodoc:
SA_FullPalette: this is a Boolean attribute. Prior to V36, there
were just 7 RGB color values that Intuition maintained
in its user preferences (playfield colors 0-3, and colors
17-19 for the sprite). When opening a screen, the color
map for the screens viewport is first initialized by
graphics (graphics.library/GetColorMap()) then these
seven values are overridden to take the preferences values.

In V36, Intuition maintains a full set of 32 preferences colors.
If you specify TRUE for SA_FullPalette, Intuition will
override ALL color map entries with its full suite of
preferred colors.

Like with everything screen-related you have to load the icons after the screen has been opened and you have to tell icon.library which screen to use to allocate pens.

But I noticed with PeterK's new icon.library the colors are correct always. :)

A lot depends on picture.datatype and type of video output AGA/CGX/P96.
Old versions incl. OS3.9 version of picture.datatype can cause funny colours on custom screens.

That's probably only when you use a Hi/TrueColor screenmode, because then my icon.library displays the 24 bit RGB colors with direct drawing onto the screen by using the CGX-function WritePixelArray(). If you switch to 256 colors or AGA you will get the same results as with the original icon.library.

Did you call LayoutIconA() -- Adapt a palette-mapped icon for display ?
