Is there any way to create a textInput box for flex mobile with inline image without using textflow ?
Basically i need a text input component , so that user can just use it as normal text input box but to it images can also be entered inline with text. To enter images user can select the image from list and that image will get inserted at the current cursor position.
If you look at any platform, there is no user experience (as far as I've seen) that lets you add images in the text input box. It's always been straight text, except for android which replaces certain text with icons (like :-) becomes an android icon). I don't think your users would expect that behaviour. If you really do need it, I would recommend you create a custom skin for your textinput box and add that feature into it, but it won't be easy to do.

We designed a web interface to display text in a scrollable element and to track scrolling events when someone scrolls to read the text. We set the textual display features using CSS. Now we have a record of what text was displayed, and a record of what the window size was (or sized if the user re-sized the window at some point). All events are timestamped. We want to develop a record of how long each portion of the text was displayed to the user as they navigated by scrolling. I thought there would be many examples of code to do this, but I don't find anything.
So, can someone refer me to a resource of how I might be able to calculate based on the font size, line width/height settings, and display size of a scrollable text window, how to determine which range of the text was displayed given a certain scrolling indicator?
Many thanks for any leads.
I can not use a Background Image because cannot fix the position of the start point.the placeholder text is centered.so it is not duplicated.
How to add an icon in the placeholder of an Entry beside using Grid or Layout. Just add it in the placeholder.
I want to make an Entry with placeholder containing an icon . Which is center in the Entry so that I can not use grid or layout to add a Image because this is not the best way.
I think I will have to make clicked event functions of the Image and the entry focus to hide the Image.
The expected result is like that:
Entry
The first way I can think of doing this:
If the icon you would like to use is a generic icon, FontAwesome is a fantastic fontkit that displays icons in the place of text. I have implemented it into Xamarin Forms many times. Here are some tutorials on how to do that:
https://www.wintellect.com/using-fontawesome5-xamarin-forms/
https://doumer.me/icons-with-font-awesome-5-xamarin-forms/
What you would do is set the FontFamily of the entry field to FontAwesome, and then add a textchanged event on text length > 0 change the fontfamily to your normal font, on text length = 0 (Place holder displayed) Change font family to FontAwesome.
The second way I can think of doing this:
Create a Xamarin Forms Custom Renderer for all of the platforms you are using. whereby you will on the native level alter how the Entry field functions to display an icon in its placeholder. To do this you will either need some native expierience on both platforms or some patience and learning about the native platforms.

I want to create a tappable button with an icon and some text.. kind of like how the map app does it. See the attached picture below.
I've currently tried having a button that is set to the Group mode for content. However, this makes the background clear and I wasn't sure if there were any better options. Another option that came to my mind was creating a table view with one cell that took up half the width but that would be very hacky as well.
Just create two groups. Then you can change the background color, add an image and text label. To make it clickable simply add a tapGestureRecognizer to the group and it will function just like a button.
i am trying to accomplish the following behavior with a QML TextArea:
I want single Words in the Text to be colored differently
I want the "select"-functions to be working for automated scrolling (user interaction is disabled)
There is a stream of text in the TextArea where one Word needs to be selected(highlighted). The user is requested to input some text elsewhere and press enter to proceed (not part of the question). After that the selection jumps to the next word and the last selected word is either colored green or red. There is only a small portion of the text visible (a few lines, managed by the TextArea height – not part of the question) and i need the text to scroll if the next word is out of that visible range .. therefore the selection is quite helpful because all interaction from the user – to scroll or select or whatever – is disabled (disabling is not part of the question)
my main problem is: if i use textFormat: TextEdit.RichText i can easily color the text how i like it to be (<font color=\"green\">{}</font>) but i cannot use the "select"-functions anymore because – as i would guess – the selection works on the "plaintext" and cannot correspond to the "richtext"-selection? Anyway selectWord() etc. does not work QTextCursor::setPosition: Position '-1' out of range is the result. But if i disable the RichText i don't know how to color the text. Maybe i could live without the selection if i could detect the current word – which would be colored blue etc. – and scroll if its out of the visible area to "fake" the selection behavior, but that's just a third option.
I would really either know how to color non-Rich Text or how to select Rich Text in a TextArea.
You can use QSyntaxHighlighter to highlight the words independent of the selection. See QQuickTextDocument and How to implement rich text logic on QML TextEdit with QSyntaxHighlighter class in Qt for more details.
I'm having this problem of adding an image to the textArea in RichTextEditor (RTE) on the fly and this image seems to "reset" the html properties of the textArea.
Better explained:
The user starts writing something in the TextArea (with Verdana in size:12 font settings). When he adds an image to the text area, the cursor right after the image gets very small and the font settings are reset to HUM777B in size:2.
How could I avoid this behavior?
It seems Flex adds additional HTML code before the image tag. If there was any way to avoid this I would be able to add my own settings to the tags.
Just before you programmatically add the image to the textArea, create a variable and store a reference to the textArea styling info. Set the styling info using this variable after you have added the image.
