devexpress fontcombo

hi there

maybe this has been answered before, if so, please let me know.

otherwise, i have strange behaviour in a small demo project
(http://www.polypoint.ch/download/wp_demo/wp_testing.zip).

the goal is to change the font of the wp-richedit at the cursor position.
from what i read in the documentation this should be straightforward
using "standard actions".

the trouble is that the font of the combo keeps changing back to the original value shortly after one manually clicks into the wp-edit. this does not work:
1. start the project
2. change the font in the combo (i.e. from arial to bookman)
=> the font in the combo is "bookman"
3. click into the wp-component and wait (1-3 secs)
=> the font in the combo switches back to arial

i'm must be missing something, but failed to see what it is. any clues
would be greatly appreciated.

best regards
christophe

good morning

I activated "USEEXPRESSBARS" as a compiler directive and did a build all.
Is there more to it that I may have missed?

I have done some further invesitigation and found that the problem is the devexpress TdxBarFontNameCombo. It reverts its font back, there was an issue posted at devexpress.com (http://www.devexpress.com/issue=Q290002) and currently it is only available through google-cache.
however, quote devexpress:
"Our developers have examined this behavior and come to the conclusion that the current architecture of our components does not allow for fixing this behavior...."
=> sorry to bother you. i will start bothering devexpress :)

I think I will yes. On that note, what is the proper way of setting the font at cursor location:
- WPRichText1.TextCursor.CurrAttribute....
or
- WPRichText1.CurrAttribute...

Or are they both the same?

Thx for all the advice. Replacing the combo with another (devexpress) combo worked out just fine.

I have a question though. I am loading a wp stream with some text (say all in "Arial") in it, and focussing on the wpedit. The cursor gets "automatically" positioned at the beginning of the text. There I retrieve the fontname through:

curFont := WP.CurrAttr.FontName;

This works fine once the cursor has been moved in the text (for example by using the arrow-keys). At the very beginning (right after setfocus) this retrieves the WP.DefaultAttribute.GetFont-Value (which would be "Times"). If I move right then left again with the arrows I do get WP.CurrAttr.FontName "Arial".

Is this expected? Why or why not?

I assume my problem is that the cursor is not positioned the way I want it (or expect it) by "SetFocus". How do I set it to the first character?

Great thanks I'll try that. I have seen some info in the help files (FirstPar etc).

I already used the events OnCharacterAttrChange as well as the OnCursorPosChange to update font-info.

Thx for your help.

Ok now I see what the problem is in my code. The CPPosition is set to -1 when I start. All the formatting takes place on that position.

Is CPPosition=-1 just the uninitialized default or does it have a special meaning to it (something like "valid for all other paragraphs, like DefaultAttr)?
