I am enjoying setting up Call tips, but have hit a couple of annoyances, at
least one of which has been mentioned in a prior posting, but with no follow up
regarding implementation.
1) Call tips seem to use STYLE_DEFAULT - at least as far as the facename and
size. This is a pain as it makes the call tip seem too imposing... it would be
really nice to either add a new predefined style, say STYLE_CALLTIP=38, or add
another message - SCI_SETCALLTIPSTYLE(int styleNum, <unused>) to determine
which style is to be used. I noticed that there was a message about fonts
earlier and Neil indicated he would accept a patch. Did anything come of this?
As far as I can tell, it involves changing ScintillaBase::CallTipShow() to
replace STYLE_DEFAULT with either a dedicated style, or with the style number
set by the container.
2) In my call tips, I like to give the user some help with the arguments. I end
up with a call tip like:
Func MyFunc(var1, var2$)
var1 Set this to 0 to cool the kettle and to 97 to be awkward.
Other number cause my blood to boil.
var2$ A list of kettle manufacturers, separated by steam.
Return The mass of an average kettle.
All Ok so far, but if we use a proportional font, nothing lines up as . So it
would
be nice to set a tab size. This could be done as part of an SC_SETCALLTIPSTYLE
(int styleNum, int TabSize)... with tabs set in pixels (we can find out how big
by using the SCI_TEXTWIDTH call).
3) The documentation for call tips should be extended to say how the call tip
font is constructed:
"The call tip is displayed using the font facename and current zoomed size of
STYLE_DEFAULT [or the style set by SC_SETCALLTIPSTYLE]. Other style features
such as italic and bold are ignored."
--------------------------------------------------
In terms of implementation, allowing the container to choose the style to set
for the call-tip looks straightforward. However, implementing a tab width looks
more involved due to the way that the call-tip is drawn. In terms of backwards
compatibility using a SCI_SETCALLTIPSTYLE must be OK. Setting a new default
style would probably be OK, but folks who set a new default style without
copying it to all styles would see differences.
Does anyone have any thoughts about this?
Would Neil accept a patch to implement any/some/all of this?
