QUESTION
Let's say you've just set some text in a spellcheck-enabled rich edit control, and the text has some spelling errors. A split second will go by, spellcheck will kick in, and then the misspelled text will get underlined. But guess what: the rich edit control will actually send an EN_CHANGE
notification just for the underlining event (this is assuming you've registered for notifications by doing SendMessage(hwnd, EM_SETEVENTMASK, 0, (LPARAM)ENM_CHANGE)
).
Is there a workaround to not get this type of behavior? I've got a dialog with some spellcheck-enabled rich edit controls. And I also want to know when an edit event has taken place, so I know when to enable the "Save" button. Getting an EN_CHANGE
notification merely for the spellcheck underlining event is thus a problem.
One option I've considered is disabling EN_CHANGE
notifications entirely, and then triggering them on my own in a subclassed rich edit control. For example, when there's a WM_CHAR
, it would send the EN_CHANGE
notification explicitly, etc. But that seems like a problem, because there are many types of events that should trigger changes, like deletes, copy/pastes, etc., and I'd probably not capture all of them correctly.
Another option I've considered is enabling and disabling EN_CHANGE
notifications dynamically. For example, enabling them only when there's focus, and disabling when focus is killed. But that also seems problematic, because a rich edit might already have focus when its text is set. Then the spellcheck underline would occur, and the undesirable EN_CHANGE
notification would be sent.
I suppose a timer could be used, too, but I think that would be highly error-prone.
Does anybody have any other ideas?
Here's a reproducible example. Simply run it, and it'll say something changed:

Answered 2021-May-10 at 15:13Use EM_CANUNDO
(maybe also EM_CANREDO
) to verify that contents has changed. I hope that spellchecker does't add any undo information.

I'm making a small CMS system in React and I have a form where users can use the Draft.js editor along with some other fields. For the question in mind, let's focus on the edit form.
The code for the editor looks like this:
...ANSWER
Answered 2021-Feb-26 at 17:35In my humble opinion, the provided solution is a bit overengineering. So let me just provide my thoughts on the questions you asked:
- I don't see the optimization in using
useImperativeHandle
as the value is stored both in ref and inRichEditor
state - the
formatToHTML
function seems to be pure function. So why not export it and use exactly before form submition instead of complicating things withforwardRef
anduseImperativeHandle
- Here is what I propose and I think it is exactly what you mentioned in the 3rd bullet:

I am working on a SwiftUI project, the functionalities it required is to make a Rich Text Editor on IOS.
The approach I am following is fairly simple, I used cbess/RichTextEditor link originally written in UIKit and import it into SwiftUI. To run the imported UIView, I wrap the view inside one UIViewRpresentable and add it into the ContentView struct of SwiftUI.
Now, I want to publish the data inside UIView and assign it to one of @state ContentView owns.
The code structure look similar to this:

QUESTION
Basically in my app I have a RichEditBox which is required to save its data on TextChanged event and load the text from saved settings OnLoaded event, after weeks of experimentation I was able to reproduce the issue in an minimal app for you guys to test.
Aim : Ultimately no matter I use dark or light theme to save the RTF text in this rich edit box, whenever it is loaded again in whatever theme it should show the correct text color in both dark and light themes. and during the running app if the user changes theme of their device, the text color should also change as expected. I am not sure how to save the rtf text here it ignores the text color maybe?
Reproduce the bug here : https://github.com/touseefbsb/RichEditBoxColorBug
- Make sure your device theme is on "Dark".
- Run the app and add some text into the RichEditBox (the textblock and button on top are just to make sure the app doesnt focus automatically on richeditbox when page loads).
- click somewhere else on screen to loose focus from richeditbox, then close the app.
- Run the app again you you'll notice the text you entered before is already there as expected, now close the app.
- Turn the theme of ur device to "Light" and again run the app, now you will notice the richeditbox seems to be empty.
- But actually it isnt empty, the issue is the textcolor is white just like the color of richeditbox while the text color shouldve been black in light theme. This can be proved just by selecting the text with cursor and notice the highlighted text appears.
Everytime you change something and try to test the whole flow again just make sure to change the key string in both Loaded and TextChanged events, to make sure entirely new RTF value is being saved and being loaded later, the key in loaded and textchanging events must always match and should be changed everytime you want to start from step 1.

Answered 2021-Jan-13 at 12:46I had similar issues trying to convert RTF to HTML from a RichEditBox
.
As long as we assume you don't allow font color changes it is not that hard. Both suggested options would also work if you allow font color changes through the document, but this introduces a lot of work and trade-off (i.e. do you invert colors selected in light theme when displaying them in dark?, certain colors look better with black background, others with white, etc.)
1. Change theITextDocument
This option is quite simple and works quite well. Underneath the RichEditBox
there is an ITextDocument
which contains the actual text (accessed through RichEditBox.Document
). After you set the text of this document you can also set the font color (it is even possible to change to font color for certain parts of the text this way):

I created inputs and they work just fine, but I need to change the name attribute for each auto added block.
For example :

Answered 2020-Dec-21 at 05:19You can use your x
variable that is incremented for each added input
and append it to the name
attribute. We'll use a 'template string'. The adjustment is name="fname${x}"
which will substitute ${x}
for the value of x

QUESTION
I just want to assign immutable, richly formatted text to RichEdit (or DevExpress cxRichEdit, which, obviously is inherited from VCL RichEdit) during design time. I know how to do a lot of formatting during run-time using Selection of text and setting attributes to this selection. But I have no need for this flexibility - I just have long text with some words in bold and there is no need to modify it in runtime, this is some information/documentation for the user.
How can I assign such text during design time? RichEdit does not have sophisticated editor (at least I can not find it) for the Lines attribute. I tried to create RTF document in Word and then copy-paste its value (text with RTF markup) into Lines attribute, but then RichEdit shows all the RTF markup. Besides, Word adds incredibly lot of RTF additional information, not just some RTF tags here and there.

I have a problem when my code outputs to a rich edit. When I click on the button to calculate everything and then display everything it doesn't output the generated ClientNum and Price. However, when I click the button for a second time afterwards it outputs everything without a cinch? Is there a problem with my code or could be something external like an anti-virus software that's messing with the output?
