[MSEide-MSEgui-talk] TIcon.Colorglyph - why doesn't work?

[Krzysztof]

Hi Martin,

I have created spinner from this site:
http://preloaders.net/en/search/spinner . I need to change color
dynamically at runtime by changing TIcon.Colorglyph but it doesn't
work. I see that it work with your embedded stock glyphs (e.g. grids
sort indicator). But in my case it is always black. I'm not sure where
is the trick, is it in bitmap format or imagelist option? Here is what
I do:

1. Pick any spinner from that site. In website creator I'm checking:
 - ImageType: APNG
 - Transparent Background: Yes
 - Keep original colors: Yes
 - Invert colors: No
 - Rest options default
2. Click "generate preloader"
3. In "additional download options" check "download as sprites"
4. Click download
5. In MSE ide prepare imagelist size to downloaded preloader size. Add
downloaded spinner, it should be nicely split to 8 frames

Use attached demo

Sorry that I'm bother you recently but I'm close to finish porting my
LCL app and I'm very happy that it is going so well :) . This issue is
cosmetic and it is realy fine if spinner will be always black but I'm
curious guy :). Tried spinner generated from font awesome with rotate
option which you added but it doesn't look good - rotate animation is
fine but pixels have offset for each angle (frame) so animation is
"shaking"

Regards

Great!

Should I use all events or pickup one? This code seems to work but
size is not correct (looks like 1/3 of expected width):

procedure TGenericListWidget.DrawTitle(const sender: tcol;
  const canvas: tcanvas; var cellinfo: cellinfoty);
var r: PMusicTag;
begin
  with cellinfo,cell do begin
r := FPlaylist[row];
if calcautocellsize then
  autocellsize.cx:= textrect(canvas, r^.Title).cx;
drawtext(canvas,r^.Title,innerrect,[tf_ycentered,tf_ellipseright]);
  end;
end;

If it's not a problem then why not :)

BTW: I'm drawing text by my self so double click on column resize
point is not handling text width and column is collapsed. Is there any
event for that? Some kind OnGetColumnSize?

Well, I'm just porting "report like" lists from my LCL app and
comparing behaviors. In LCL (Qt,Gtk,Win), lists are sorted by clicking
on column header and never saw indicators on not sorted columns. This
is something you have to get used, no problem. User just always can
sort on all columns in my app so showing possibilities is overloaded
and showing indicator only on sorted column is little more "eye
catching" ;)

> Not supported. Is another flag necessary? ;-)

That would be handy :)

Ahh, sorry. Forgot that long time ago I tested this package:
mseuniverse/add-on/lib/addon/compdesigner . I'm not using it at all,
so remove it from regcomponents solved problem

Remove the dco_colsort flag but then the sorting can not switched on by 
clicking on that header. Why do you dislike indication of the possibility to 
sort?

Works for me. What is "compdesigner.pas"? I don't find it in MSEide+MSEgui 
source tree. og_noresetselect has been replaced by optionsgrid1 
og_noresetselect1 several versions before.

1. How tu disable showing sort indicator on not sorted columns?
Currently if column is not sorted then icon is grayed / disabled. I
would like to show indicator only on sorted column
2. How to force sort on column click, not only on indicator icon?

Please additionally activate TCustomGrid.OptionsGrid og_sorted and 
og_customsort (git master 055154f363ab422e5ce88af018a2a68bba4da8e6).

Because FPC does not search as documented I reversed the order for the -F* 
parameters. Please activate 'Project'-'Options'-'Make'-'Directories'-'Reverse 
directory order' for old behaviour (git master 
055154f363ab422e5ce88af018a2a68bba4da8e6).
