Scrolling TextBox with HardwareKeys

[Elrick]

Hello! Is there a way to scroll text in TextBox with Up and Down keys?

 

[Erel]

Are you referring to a single line textbox or multiline textbox?

 

[Elrick]

I'm using a multiline textbox. I want to scroll large text in it by pressing hardware keys and not by moving scrollbar :sign0085:

If the textbox is focued then pressing the up/down keys should scroll the text.

Not absolutely so. It scroll the caret, not the text. And yes, when the caret is in bottom of the TextBox, text will scroll. But if i need to scroll text up, i'll have to move caret from the bottom to the top. And the caret's blinking is so annoying But i want to make something like...err...text reader, where the text will scroll line-by-line by pressing HardwareKey. I use TextBox instead of something different because i need to copy\paste text.

A better solution will be available in a day or two.

Using the new SendMessageToControl method of the updated Hardware library you can send scroll messages to the textbox.
First download it here: http://www.b4x.com/forum/showthread.php?t=2154

I've used 4 buttons: PageUp, PageDown, LineUp, LineDown
You could use a HardKey object to catch the hardware buttons and then send the scroll message.

Erel, this is exactly what i need! Thank you! And it's a nice joke with text to scroll in demo
And another question - where can i find the description of all system messages ?
