font size RTB control

[vb_lover]

I am working with an RTB control,

Does anyone know how to get the current font size using an API? or a means other than rtb.selfontsize?

rtb.selfontsize only contains font size AFTER the character was typed or cursor moved. I need to know the fontsize BEFORE the user types, so if the fontsize changes, before the user types a character...i want to know what the font size is.

What are you trying to do? RTB's have a default font, if there's nothing in it. Each character can be different, so how would you know what one was before it was set?

[vb_lover]

DG: i already explained what i wanted to do in the first post. And since i mentioned using .selfontsize, that should of been your hint that i alreadly knew any character could have its own height AND that i was not trying to get the default font since that is an entirely different property.

Anyway...

in case anyone wants to know...its em_getcharformat, yHeight

[dglienna]

You mean sendmessage? I was thinking that, but what is the fontsize of an empty rtb?

AFAIK, the current font size is represented by the SelFontSize property. i think his referring to the character/font height in pixel which is different since SelFontSize is in Points.

Lovely SendMessage()

@vb_lover: Could you post the complete call required here?

[vb_lover]

DG: i never said i had an empty RTB, not sure why you thought this. But BTW, an empty RTB can have a fontsize set of the next character that is going to be typed! There can be conditions in an RTB that when a font changes the .selfontsize property does not reflect the fontsize of the character that is going to be typed. The .selfontsize only shows the current current font size after the character was typed, or the cursor was moved over another character.


The call is sendmessage(rtb.hwnd, em_getcharformat2, scf_selection)

its simple to convert to points: yHeight \ 20

Sorry, I don't quite understand.
What is the fourth parameter, because Sendmessage() always takes four, and where is the result goin' ta come out? What is scf_selection?

[vb_lover]

corrected: sendmessage(rtb.hwnd, em_getcharformat, scf_selection,cf2)

[WoF]

Ok, SCF_SELECTION tells to get the format of the current selection.
And what is cf2? What data type is the result?
Sorry for asking. Pure curiousity.

[vb_lover]

cf2 is a type structure as CHARFORMAT2
and the results of the sendmessage are returned within the structure.
In this case yHeight.

I see. Thanks for the info.
