QUESTION
How could I create a listview at the current caret position in codearea while typing as autocompletion in javafx? So far I locate the word that is currently being typed and I see if that word is contained in the array. This is the code I have so far. Thank you in advance!
String[] keyphrases = new String[]{"int main(){\n}", "cout", "cin"};
ANSWER
Answered 2021-Apr-19 at 23:48If you are asking about how to show a ListView at the caret position, please check the below approach. This is a general high level approach of showing the ListView at the current caret position. You can relate the logic and change as per your requirements.
I believe this will give you the required basics about how to approach. Having said that, there can be many other better approaches.
The core idea is to rely on the caret node (Path) bounds, rather than doing the complex computing for finding the location of caret in the text.

I am working on a Blazor Server application that uses a code editor. For code editor I am using CodeMirror. The text area is rendering fine on the Blazor page but the data binding is not working with the corresponding C# field.

QUESTION
How can i replace some (more than one) hexadecimal into decimal? Which methods need to use?
Example text:
...ANSWER
Answered 2020-Aug-17 at 23:29The reason you get both numbers twice in the output is because you passed fhex into replace, where it expected a string, so it converted [90, 131] into "90,131". Instead, you want to pass the converted number in, which then gets converted to the string you actually want.
An additional problem is that if you pass the hexadecimal regex in as the first parameter to replace, then it will match all the hexadecimal numbers, so you want to pass something that only matches the string you want to replace with the number you currently have. Luckily, the string itself does that! So instead of replacing each fhex[i] value with a number, if you keep the string around, and put the number in a separate variable, you can pass the original string and the new number value into replace like so:

Hi I’m working with ionic 4 and angular 8 and I tried to make an ecommerce application and when I tried to load the addresspage book of customer’s address I got two errors that i didn’t understand where did it come so I put below the stack trace of the console , I’m running my app in chrome if somone could help me it will be helpful for me in order to continue
i put below the file concerned
addressViewPage.html
...ANSWER
Answered 2020-May-25 at 02:45You are getting undefined "here" in console because the code is running outside of subscribe and at this place address is not defined. Also you have not pre-initialized the address field and trying to use its firstname property in html ngModel is causing the error.
You need to initialize the address first with dummy value or load the form when address is initialized with *ngIf Post Api successful call , your address form will be updated.
QUESTION
I am using CodeArea from RichTextFX in my code editor. I need to show context menu on right click and fill it based on the text where mouse is pointing. Like if I right click a function call, there will be "Go to declaration" in the context menu.
To do that I need to get character index where the mouse is pointing. For MouseOverTextEvent there is the getCharacterIndex() method, but there is no such method in ContextMenuEvent or MouseEvent.
Saving the last index from MouseOverTextEvent is not a good option for me because I use MouseOverTextEvent for showing popup messages and this event has a 1 second delay (used setMouseOverTextDelay).
How can I get the character index for this right click event?
...ANSWER
Answered 2020-May-22 at 18:11The hit(...) method inherited from GenericStyledArea gives you access to the index of the closest character, given the x and y coordinates in the code area's coordinate system (which you can readily get from the mouse event).
QUESTION
As in the above im trying to compile a QT5 project inside of QT Creator with cmake and want to add the antlr package.
Infos: Qt 5.12.8, Antlr 4.8, Compilers tried: mingw gcc|g++ , msvc 2015,2017 System: Windows / Linux both do not work
For including Antlr 4.8 i use the provided CPP Package to build Antlr from Source
This is the project i am working on. https://github.com/MrDiver/ArmSimulator/tree/ArmParser/src/asmeditor/AsmEditor
i include antlr4 with the following https://github.com/MrDiver/ArmSimulator/blob/ArmParser/src/asmeditor/AsmEditor/CMakeLists.txt#L14-L21
and normally it works perfectly fine when i compile something with it. But this time when i try to include the header files for antlr i get this error message
...ANSWER
Answered 2020-Apr-19 at 18:47The problem is that Antlr has methods like "emit" that conflict with the Qt reserved word "emit". The solution is to disable the flag "no_keywords" (in qmake add CONFIG += no_keywords, and in CMake add add_definitions(-DQT_NO_KEYWORDS)) as indicated by the docs. Then you must make the following conversions:
QUESTION
I'm trying to use RichTextFX but when I do try to use it I get a long error (see below). I'm using IntelliJ IDEA 2018.3.4, JDK 8 and Gradle version 4.8.1. My current way of trying to install it is I downloaded the jar (richtextfx-0.9.2.jar) and move it into a folder in the project. I then add the jar as a library and save. Then I go to my JavaFX file, and make a new Code AreaCodeArea c = new CodeArea(); This will result in a large error. I think there is an error with gradle installing. I haven't used it before so I'm very new at it.
I am able to use the actual files (when not compiled into a JAR) to run the demos provided. This is in a different project, and the gradle libraries are added as external libraries when the project was created. The project I'm working on however does not have these extra external libraries.
Any support on what to do would be greatly appreciated. Thanks!

...ANSWER
Answered 2019-Feb-23 at 21:01You can't just download the JAR for RichTextFX and add it to your project. RichTextFX itself has dependencies that only downloading the JAR won't provide. In your case, you're seeing an error saying the Flowless dependency is missing. However, you don't have to download the JAR files yourself—that's what Gradle is for. You just need to add the dependency to your build script; the README of RichTextFX provides an example1.
QUESTION
I have a CodeArea (org.fxmisc.richtext.CodeArea). It support the hotkeys CTRL-Z for undo and CTRL-Y for redo.
I am inserting a text programmatically at the caret position. Now when I hit undo, this undo goes further than undoing the text insertion, it undoes the creation of the file so that the code area is empty again.
I would like to create an undo save point before I insert the text. There must be some way to do this (I hope!).
