Field with placeholder/hint text

[stam]

Hi all,

I've needed a field for a project that shows hint text and have pretty much got there but there are a couple of very minor snags.
The snags are minor and this works very well, but would be nice to make it perfect

Project available here: https://github.com/stam66/skPlaceholderField
This includes a small UI as a control panel to modify the field's custom props. The stack is set up as a palette and can be used as a plugin (recommended) - you can adjust the 'prototype' field and copy it to your stack - or if you already have an skPlaceholderField in your stack you want to edit, select it in the IDE and click the arrow button top left.


The functionality I required

• If field is 'empty' it shows the hint text in a different style to 'normal' text entry (eg italic and light grey)
• On entering field nothing changes but on typing or pasting text, the hint text disappears and the text style changes (eg black, plain)
• If text is deleted the placeholder text reappears before exiting the field
• For fields/texts that are within the size of the field it enters the text vertically - but if the formatted text exceeds the height of the field, the text should be vertically aligned to top instead.
• Option to resize text as a function of field height (i.e. as a percentage of field height)
• Placeholder and normal text style changes based on whether the field background is light or dark
• Configurable properties - not hardcoded in handlers

The 2 minor issues
1. The way my code handles entering text is if the he placeholder text is showing, it removes it when the user types so that only the user's text (in normal text style) shows. To do this, I need to be able to check for presence of the placeholder text and remove it - which works well. But if the user clicks in the middle of the placeholder text that inserted text there which makes it very difficult to do this, so I set the selection to the start of the field which then works seamlessly.

Weirdly, putting code in openField did not help, the best I can do is with

Code: Select all

on selectionChanged
    if fieldIsEmpty() then select before me
end selectionChanged

where fieldIsEmpty() is a function that returns true if the field is empty or if the field is only showing the placeholder text.
This works - but while the mouse is down, the cursor is inserted at the mouseLoc and on mouseUp jumps to the start of field.
On click this is isn't that noticeable but on persistent mouseDown it really is... it's a cosmetic issue but it's bugging me

Question: How can I immediately move the selection to the start of the text on mouseDown (mouseDown and openField don't work...)


2. Setting the text programmatically: Because it isn't possible to create a setProp-style handler for the field's text I can't trigger a textStyle change when setting text programmatically, but since this is triggered on field events this works:

Code: Select all

set the text of field "skPlaceholderField" to "some text here"
send "exitField" to field "skPlaceholderField" -- triggers text formatting

Question: is any way for the field to be made aware that its text has been set programmatically to simplify this?

Not sure if there is a way around these minor snags, but very grateful for any suggestions...
I'll post the code in a separate post to make this more readable

Other than the 2 minor issues mentioned above this works very well.

CUSTOM PROPERTIES
To manage this functionality I've used a number of custom properties:

TEXT
uPlaceholderText -- the hint/placeholder text to show
uScaleFactor. -- how to scale the text in proportion to field height
uPlaceholderTextStyle -- the textStyle for the placeholder text
uNormalTextStyle -- the textStyle for the normal text
COLORS
uPlaceholderTextForLightBackground -- the placeholder/hint textColor when the field has a light background
uPlaceholderTextForDarkBackground -- the placeholder/hint textColor when the field has a dark background
uTextForLightBackground -- the normal textColor when the field has a light background
uTextForDarkBackground -- the normal textColor when the field has a dark background
OTHER - self explanatory
uBorderColor
uBorderWidth -- needed because with width = 2 (the default), LC does the funky to imitate the OS, at least on MacOS
uBackgroundColor

I didn't parse through your entire script but I can offer a simpler one I use. I think it's typical for the field prompt to go away when the user clicks in the field, that is, on openField. At least, that's how most of the ones I've seen on mobile work. At any rate, here's what I use in the script of a field. I use a custom property "cDefaultPrompt" but it could just as well be a constant.

Code: Select all

constant kDisabledColor = "138,138,138"

function textFldEmpty
  get the text of me
  return (it = "" or it = the cDefaultPrompt of me)
end textFldEmpty

on openField
  if textFldEmpty() then
    put "" into me
    if the backcolor of me = "255,255,255" or the backcolor of me = "" then
      set the textcolor of me to empty
    else
      set the textcolor of me to "255,255,255" -- color bg
    end if
  else -- scripted text entry
    set the textcolor of me to empty
  end if
end openField

on closeField
  resetDefaultText
end closeField

on exitField
  resetDefaultText
end exitField

on resetDefaultText
  if textFldEmpty() then
    put the cDefaultPrompt of me into me
    if the backcolor of me = "255,255,255" or the backcolor of me = "" then
      set the textcolor of me to kDisabledColor
    else
      set the textcolor of me to "255,255,255" -- color bg
    end if
  end if
  centerTextVertical
end resetDefaultText

on centerTextVertical
  put round(the effective textheight of me * .66) into tUnderHang
  set the topmargin of me to (the height of me - (the formattedheight of line 1 to -1 of me) + tUnderHang) div 2.5
end centerTextVertical

You'll probably want to add more specific text styling and flesh out some other properties, but I think using openField would manage the 2 issues you mention. I'm not sure why openField doesn't work for you, it seems okay in my stack. But like I said, I didn't go through your entire script.

[jacque]

Playing with this, for scripted text:

Code: Select all

on scriptedText pText
  put pText into me
  openField
  resetDefaultText
end scriptedText

[stam]

Thank Jacque

Using openField was my initial approach - but it doesn't conform to what I normally see in software, ie deleting all the text so the field is empty I expect/hope to see the hint text again but with openField, you have to exit the field to show the hint text.
My current implantation shows/hides the hint text as needed while typing.

The only issue is that you can select the hint text and click in it, which is visually unappealing.
Functionally this can't cause any issues because typing in the field will only show what the user typed (I realised the below fixed the risk of typing in the middle of the field)

Code: Select all

on keyDown pKeyName
    if the text of me = the uPlaceholderText of me then set the text of me to empty
    pass keydown
end keyDown

It is a cosmetic issue as the user can still see the cursor/selection until they release the mouse. This mitigates it a bit but the cursor/selection is visible until the user releases the mouse:

Code: Select all

on selectionChanged
    if fieldIsEmpty() then select before me
end selectionChanged

What I don't understand is why the following doesn't work, as it would completely addressed this issue:

Code: Select all

on openField
    select before me
end openField

[jacque]

Does this do what you want?

Code: Select all

constant kDisabledColor = "138,138,138"

function textFldEmpty
  get the text of me
  return (it = "" or it = the cDefaultPrompt of me)
end textFldEmpty

on openField
  if textFldEmpty() then
    put "" into me
    if the backcolor of me = "255,255,255" or the backcolor of me = "" then
      set the textcolor of me to empty
    else
      set the textcolor of me to "255,255,255" -- color bg
    end if
  else -- scripted text entry
    set the textcolor of me to empty
  end if
end openField

on closeField
  resetDefaultText
end closeField

on exitField
  resetDefaultText
end exitField

on rawKeyDown pKey
  if me = the cDefaultPrompt of me then
    openField
  end if
  pass rawKeyDown
end rawKeyDown

on rawKeyUp pKey
    resetDefaultText
end rawKeyUp

on textChanged
  resetDefaultText
end textChanged

on resetDefaultText
  if textFldEmpty() then
    put the cDefaultPrompt of me into me
    if the backcolor of me = "255,255,255" or the backcolor of me = "" then
      set the textcolor of me to kDisabledColor
    else
      set the textcolor of me to "255,255,255" -- color bg
    end if
  end if
  centerTextVertical
end resetDefaultText

on centerTextVertical
  put round(the effective textheight of me * .66) into tUnderHang
  set the topmargin of me to (the height of me - (the formattedheight of line 1 to -1 of me) + tUnderHang) div 2.5
end centerTextVertical

on scriptedText pText
  put pText into me
  openField
  resetDefaultText
end scriptedText

Thanks Jacque

No - as I mentioned this was my initial approach.

The reason I don’t prefer this is that I still want the placeholder text to show when the user enters the field but hasn’t typed anything.
And if the user deletes all inputted text, the placeholder text should reappear even if the user has not exited the field.

With your (and my initial approach) the hint text disappears on entering the field and before typing anything, if I understood your code correctly.

I also don’t understand why I can’t set the selection on openfield…
I’ve been thinking of trying “before openfield” in a behaviour script, but as usual been to busy with my day job…

[jacque]

My version does insert the prompt when the user deletes any existing content. If you want the prompt to disappear on the first keystroke rather than when the field opens, then you could remove my openField handler and adjust rawKeyDown:

Code: Select all

on rawKeyDown pKey
  if me = the cDefaultPrompt of me then
    put "" into me
  end if
  pass rawKeyDown
end rawKeyDown

I think this covers all instances while the user is typing. You mentioned you noticed a visible change/glitch but I don't see that on my Mac. If you do see it, you could lock the screen briefly.

I'm not sure why you can't use openField to do your setup, but if that's important I suppose you could use a send-in-time to effect the selection. The above rawKeyDown handler doesn't need a selection; the first key press removes the prompt.

[stam]

I think this covers all instances while the user is typing.

Yeah, I mentioned above that I did exactly that, so there is no functional problem, only the issue that the cursor/selection is visible until the mouse is released. I used keyDown instead (works just fine)

Functionally this can't cause any issues because typing in the field will only show what the user typed (I realised the below fixed the risk of typing in the middle of the field)

Code: Select all

on keyDown pKeyName
    if the text of me = the uPlaceholderText of me then set the text of me to empty
    pass keydown
end keyDown

I suppose you could use a send-in-time to effect the selection. The above rawKeyDown handler doesn't need a selection; the first key press removes the prompt.

That's a great suggestion, thank you - will test it out

Many thanks

Alas, further testing does not resolve this minor cosmetic issue (cursor/selection showing until mouse is released)

Trying to affect mouseDown in either openField or mouseDown directly does nothing until the mouse is released.
Sending in time to affect selection does not work while the mouse is down (when sent from openField or mouseDown)
Changing the script to a behaviour and using before|after openField|mouseDown has no effect until the mouse is released.

Seems like openField itself stops all processing until the mouse is released (tabbing into the field was never an issue, only clicking in the default prompt text).

I'm not sure there is a way around this to keep the prompt text showing after entering the field but before the user types, without using a 2nd field/label.

On the other hand, using a label field I could do something like this: https://www.youtube.com/watch?app=desktop&v=PTGnpXbMU1U
Hmmmm....

Stam,

In Livecode Create there is a "widget.materialfield" which behaves like the field in the link you posted. It is pretty neat and I guess it should show up in the next iteration of LC 10 DP.

materialField before mouseDown.png (22.94 KiB) Viewed 34003 times

materialField after mouseDown.png (8.69 KiB) Viewed 34003 times

The widget is extremely configurable. It is not blocked by the mouse being down in the field.

Of course that does not solve your current problem.

Kind regards
Bernd

Stam,

Out of curiosity I played with this for a short while, I made the following changes targeting the field's autoHilite and it seems to work as far as I can tell, but obviously you'll need to test thoroughly as there may be other scenarios where you need to set the autoHilite to true or false.

Hope this helps, at least a little.

Paul

   return (the text of me is empty or the text of me is the uPlaceholderText of me)
   set the autoHilite of me to false -- Blocks the ability to highlight text
end fieldIsEmpty

Hi Stam,

I also gave this a try, I don't know if it meets all your requirements. The whole thing is a bit tricky...

Kind regards
Bernd

Thanks both - I won’t be able to look at your solutions until the weekend now (on-call again), but am eager to test!

Thanks Bernd, but doesn't quite do what I wanted - which is for the hint text to stay visible after entering the field but disappear if the user types anything.

This solution is quite similar to what Jacque posted, which again is similar to my initial attempts - which is to hide the placeholder text on openField.
I've been using such a field for some time but was more annoying to edit for specific use cases and this was an attempt to generalise (the idea is to eventually make it a script widget).

In truth I've "over-engineered" this a bit and will greatly simplify (too may properties!) - but the requirements I wanted to use (mainly to stay in line with commercial software we use) are:
1. Show the placeholder text with different style/color
2. on openField the placeholder text stays visible until the user types - and 'normal' text appears with different style/colour to the placeholder text.
3. If on typing the field is empty the placeholder text should again become visible and styles should change again.

All of these things work exactly and correctly with my initial posting.

The slight glitch is that while the mouse is down on clicking in the non-hilted field, the cursor remains visible and can be the middle of the placeholder text - but on releasing the mouseButton, everything is correct again. If just clicking the field, you wouldn't even notice it, but it's an annoyance

It's truly a minor cosmetic issue - but one which could be avoided if only the cursor could be moved to the start on clicking the field. There is probably a solution I'm overlooking...

Dear Paul,
thank you for the excellent suggestion - but I'm not sure that will do it. I've not had time to actually test, but if I read this correctly, your code will leave auto-hilite on if exiting the field even if the placeholder text is showing, which then doesn't help. And if autohilite isn't on, you can't enter the field
Or maybe I didn't get it...

Thanks both
Stam
