InputBox
#1
I wrote my own version of inputbox. Its limitation is that it is only intended for a resolution of 1920x1080 (my default), so it was satisfactory for the program for which it was intended.

It supports marking and deleting part of the text, the clipboard and scrolling on the monitor if the dialog is caught by the mouse by the upper edge. Maybe it could be of interest to someone.

Code: (Select All)


Screen _NewImage(1920, 1080, 32)
Cls 'need for black with alpha 255 in background (or can be used image)
_FullScreen


D$ = "programmer"
N = Val(InputBoxZ("Window title", "This program now tests:", D$, 1, 0))
_Display
Print N, D$ 'N = buttons status, D$ = text inserted in box
_Display
End



Function InputBoxZ$ (Tit As String, Message As String, Default As String, DefaultVal, BoxType)
    'designated for 1920 x 1080 resolution only!

    'ESC = -1; OK = 1; CANCEL = 0

    B.Height = 125
    B.Width = 351
    B.X = B.Width \ 2 - _Width \ 2
    If B.X < 0 Then
        B.X = _Width \ 2 - B.Width \ 2
    End If
    B.Y = B.Height \ 2 - _Height \ 2
    If B.Y < 0 Then
        B.Y = _Height \ 2 - B.Height \ 2
    End If

    'It saves the background in ram during the dialog, nothing
    'else happens until it is confirmed or finished, it is not a pass-through function
    Backgr& = _CopyImage(0, 32) '
    GPos = _PrintWidth(Default)
    t$ = Default$

    Do Until Done
        _PutImage , Backgr&, _Dest

        Select Case K&
            Case 27: InputBoxZ$ = "-1": Exit Function 'After Esc return -1

Well that's nice!  I was starting to make something like this, now I don't have to!  

Thanks for sharing your work.

There is one built-in, can you guess it's name? Big Grin

Yeah, I've used it. Smile  It's nice to have a custom looking one though..  Also, for some reason, the builtin dialog boxes interfere with my programs when in _fullscreen.  (my post about that).

Exactly. The built-in InputBox sometimes hides behind the program screen and there are other reasons why I wrote my own version. What is interesting is that the _MessageBox never hides behind the program window (with the correct combination of _AutoDisplay and _Display), but this approach did not help me with the _InputBox.

Instead of criticizing it, I simply wrote my own solution.
Well, it will require writing one more extensive function. This is what I plan to do in the foreseeable future, and the MessageBox should properly consist of it.
The output of the function on the screen will be... a cursor. Yeah. It will be let's say 500-700 lines of code and the output will be a flashing cursor! Smile
I'm not kidding. Imagine why: You draw dialog boxes with the LINE command, it goes fast. Now imagine a form with text. There will be (on that form) for example a field: Name, another field: surname, another field with address and so on. With the what do I want to write function, you just enter the starting position, the number of characters, maybe the font style - and in fact, most of what you need for this already contains a description of the behavior of the cursor in this program, you just need to pull it out and adapt it. Input does not respond to the mouse and such a thing is missing here. Come to think of it, actually Input can't even be (directly) placed on the screen outside of text commands with the Locate command, isn't there something like InputString (derived from PrintString) in graphics coordinates? Sure, one could manipulate the graphic output of the Input command via PutImage.... but since it's already so well described, tomorrow I'll try to write something along the lines of what I'm describing here.

Hi BPlus, I'd rather be interested in something you don't have yet Smile

Of course, if you want, show your version, I'd love to see it. Big Grin
