RTF ability
« on: May 21, 2018, 06:45:20 am »
Hey all,

Doesn't Lazarus have an RTF Editor that it comes with? If not which one is considered the 'best' to use?
If it 'depends on use' why would you pick one over the other?

Thanks,

Chris

No, its not cross platform.

the one that fits my needs but that doesn't say much about yours though.
If it 'depends on use' why would you pick one over the other?
You have things backwards, you specify your requirements and we try to recommend a suite closer to them, as far as I know there isn't a single package that supports 100% of the rtf features.
Good judgement is the result of experience … Experience is the result of bad judgement.

Indeed, not even the MS RichEdit control supports full RTF.... (funny and true)

Both of these are / have Memo like components capable of dealing with RTF
http://wiki.freepascal.org/KControls
http://wiki.freepascal.org/RichMemo

In KControls/Kmemo for example, you can load an RTF file, it displays most (?) of the markup and you can save a file from its contents. Out of the box, you can edit the content but if you want to play with the markup, you need to implement that yourself.
There is an example of doing so. It (the example) does most things nicely but sucks at bullets.

KMemo is 'cross platform' Linux, Windows and Mac, I have not tried to go beyond that.

I have build a medium sort of project (~7K lines of .pas) on kcontrols because of its cross platform credentials. I suspect RichMemo would be faster but for my purpose, it has a number of incomplete bits.

When I started, the author of KControls seemed quite keen to help but perhaps not as active now.

Okay basically I'm looking for an editor where someone could do some typing, and then I want to be able to convert that into HTML, with the correct tags.

I'll look at the KControls, thanks :)

Download the sourcecode of wordpad  to see how Microsoft does it: http://download.microsoft.com/download/4/0/9/40946FEC-EE5C-48C2-8750-B0F8DA1C99A8/MFC/ole/wordpad.zip.exe

The fact that it has "ole" in the path, probably means it instantiates the richedit control. IOW those sources don't contain the actual core RTF editor.

And he would be wrong. Its a simple self extracting zip, download and test it for your self before you start pointing fingers, or just because you are a bit dusty around the ears you thing you earned the right to accuse with out proof?

So I'm looking at KControls, and while compiling the package it had a compiler error in KMemoRTF at line 4030, which says

C := UTF8Copy(AText, I, 1);

Is there something else I need to install before I install KControls? I've checked the readme files and was unable to locate anything.

Chris, you are installing it as a package into Lazarus ?

Did you get the bitbucket version ?  He has stopped formal releases, just get the latest bitbucket revision.

What was the actual compiler message ?

I'd actually gotten it from his site as there was no mention of a BitBucket version :) Getting that version now https://bitbucket.org/tkweb/kcontrols for anyone who finds this later on :)

After looking again, I see it does have a link to BitBucket, I just missed it the first few times :)

It is not done (anymore) and you should know that. My ears are perfectly OK. I wonder why MS still has this on their websites. It should be considered a security risk. I filed a report against it. It will disappear shortly because of that. It is against MS own policies. (and they tend to do what I say, although I am the self-confessed village idiot on this forum... O:-) )

I apologize in advance, I realize this question is likely off topic from the previous question I asked, and possibly off topic for this board.

However in the KMemoEditor demo, it largely just uses the TKMemoFrame which is a pre-defined part of the component. If I wanted to expand upon it, say add my own functionality I should be able to right?

For example, the main menu is installed with:

Menu := FFrame.MainMenu;

How would I add say another Menu to it? I did try creating a Menu on the form, and use:

Menu := FFrame.MainMenu + MenuItem1;

However, this got me:

Main.pas(48,27) Error: Operator is not overloaded: "TMainMenu" + "TMenuItem"

How would I combine the two? (Adding TMainMenu + TMainMenu didn't work either).

Thanks for the help in advance,

Chris
