seems to do the interesting things It will look up fpdoc and comments
and do everything to create a useful hint.
I assume this is the "correct" way of creating the contents of a hint
window. I was initially hoping there would just be some hint window
class that i can just instantiate anywhere and just have to give it the
source code position (or whatever type of data is usually used to denote
a piece of code) but it seems to work differently. It seems to first
create the hint contents and then later use them for a hint window to
fill it.
Would I have any chance to try and use the above method to create the
hint string in the code browser window? I remember having seen there a
node variable that has a TCodeBuffer somewhere in it and also X and Y
seem to be accessible. Would this be possible? From where do I get a
TCodeHelpManager object? Is there already one around somewhere that I
can simply access or do I have to instantiate my own?
Despite this not being code familiar to me, I had a quick look through
the stuff you already found:
I am sure someone with more knowledge will comment on it, but until then:
From
ide/main.pp line 15060
procedure TMainIDE.OnSrcNotebookShowHintForSource(SrcEdit:
TSourceEditor; ClientPos: TPoint; CaretPos: TPoint);
TIDEHelpManager(HelpBoss).GetHintForSourcePosition(ActiveUnitInfo.Filename,
CaretPos,BaseURL,SmartHintStr);
HelpBoss is a gobal variable in the Unit HeplManager, it seems to be the
best point to start getting contnet from.
- BaseURL,SmartHintStr are out param
- you don't need ActiveUnitInfo, only the filename.
you can get a unitinfo, if you have the editor: AnUnitInfo :=
Project1.UnitWithEditorComponent(AEditor);
// project1, is a global var too in Unit Project
// project1 is generally a good point to get the unitinfo from
So (full-)filename and caretpos, and you can get content
----
As for creating the hint window, not sure what the easiest, best way is,
but there is an example here:
ide\sourceeditor.pp line 6200
procedure TSourceNotebook.ActivateHint(const ScreenPos: TPoint; const
BaseURL, TheHint: string);
It's a few lines only.
