I have a rectangle with some text on it defined as a button symbol.
My problem when using the button is that the rectangle does NOT resize but keeps its dimensions. And when I resize the button the text font changes too.I have buttons with short text and some with very long texts. Currently the ones with long text the rectangle is not long enough to accommodate the whole text.
Anybody know how to make a button grow or shrink with text one enters at instance level?
I ended up duplicating the button symbol and making the rectangle much bigger as I found now way of scaling whatever symbol background scale with the text

I am using Qt via PySide6/PyQt to create a QTextEdit widget which fills the main window. As it accumulates text from the user, I would like to dynamically zoom out (using .zoomIn / .zoomOut) to keep all the text visible on screen at once.
I am not quite sure how to go about detecting if the text is overflowing in the text box.
Is there a Signal for this or some other obvious way to detect this that I am not seeing?
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.
Is there any property for xamarin forms Button to reduce the gap between Button image and Button text? I tried to use custom renderer, but I'm not sure which property should be set to reduce gap between image and text.
Adding more detail for clarity:
I have a Button that is of complete width of screen and a defined height. I have image and text property set for Button. While rendering, there is gap between image and text. I need to display text next to image without gap.
Any help would be really appreciated.
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.

Hi Guys,
I am trying to make a text editor in Flex.
i can move image on mouse click.
Problem is it moves with the key up or down handler. But it moves out of text area after the last line in textarea. And it also doesn't move with scroll.
Pls give suggestions for these problems.
Thanks.
Regards,
Shivang
You may want to increase the white space of your 'text editor'. Just have numbers up till person entered text. That way when you move to the bottom you are not moving outside of the textArea.
would need more example of what is going wrong with the key up or down handler. What events are you trying to capture? How are you dragging the image?
good luck.
