 Posted: Wed Sep 10, 2008 10:00 pm Post subject: Rich Text Box and Buttons and events, oh my..... |
 |
|
I have a need to have a button visible but disabled until a user scrolls to the end of a rich text box. Reaching the end of the text box should enable the button on the form. the whole 'read to the end before you can click accept' process.
I don't see any events associated with the Rich Text Box that I could use to find the end of the filed and trigger the Button to be enabled.
I'm open to suggestions here...
Thank you in advance!

Great question! Going to investigate some options today. Anyone else try scripting this yet ?

Here's a scriptlet for those that want to attempt a solution. Looks "challenging" to say the least ...
| Code: |
Break On
$System = CreateObject("Kixtart.System")
$Form = $System.Form()
$Form.Size = 640, 480
$RichTextBox = $Form.RichTextBox()
$RichTextBox.Location = 10,10
$RichTextBox.Right = $Form.ClientWidth - 10
$RichTextBox.Bottom = $Form.ClientHeight - 50
$RichTextBox.Anchor = 15
$RichTextBox.Text = GetLegalText()
$AcceptButton = $Form.Button()
$AcceptButton.Center
$AcceptButton.Top = $RichTextBox.Bottom + 5
$AcceptButton.Text = "I Accept"
$AcceptButton.Enabled = 0
$Form.Center
$Form.Show
While $Form.Visible
$= Execute($Form.DoEvents)
Loop
Exit 0
Function GetLegalText()
Dim $i
For $i = 1 to 100
$GetLegalText = $GetLegalText + "This is line " + $i + @CRLF
Next
EndFunction

k, heres a first stab ...
| Code: |
Break On
$System = CreateObject("Kixtart.System")
$Form = $System.Form()
$Form.Size = 640, 480
$Form.Text = "Attention! Legal stuff here!"
$Form.FontSize = 10
$Label = $Form.Label()
$Label.Location = 10,10
$Label.Width = $Form.ClientWidth - 10
$Label.Text = 'Read the following text. Press PAGEDOWN for more. Click "I Accept" when done.'
$RichTextBox = $Form.RichTextBox()
$RichTextBox.ScrollBars = 0
$RichTextBox.Top = $Label.Bottom + 5
$RichTextBox.Left = 10
$RichTextBox.Right = $Form.ClientWidth - 10
$RichTextBox.Bottom = $Form.ClientHeight - 50
$RichTextBox.Anchor = 15
$RichTextBox.Text = GetLegalText()
$RichTextBox.OnKeyDown = "RichTextBox_KeyDown()"
$TargetSelectionStart = CalculateTargetSelectionStart($RichTextBox)
$AcceptButton = $Form.Button()
$AcceptButton.Center
$AcceptButton.Top = $RichTextBox.Bottom + 5
$AcceptButton.Text = "I Accept"
$AcceptButton.Enabled = 0
$AcceptButton.OnClick = "AcceptButton_Click()"
$Form.Center
$Form.Show
$RichTextBox.Focus
While $Form.Visible
$= Execute($Form.DoEvents)
Loop
Exit 0
Function GetLegalText()
Dim $i
For $i = 1 to 100
$GetLegalText = $GetLegalText + "This is line " + $i + @CRLF
Next
EndFunction
Function RichTextBox_KeyDown()
If $TargetSelectionStart = $RichTextBox.SelectionStart
$AcceptButton.Enabled = 1
$AcceptButton.FontBold = 1
Endif
EndFunction
Function AcceptButton_Click()
$Form.Hide
EndFunction
Function CalculateTargetSelectionStart($TextBox)
$Len = Len($TextBox.Text)
$Rows = UBound(Split($TextBox.Text,CHR(10)))
$CalculateTargetSelectionStart = $Len - $Rows
EndFunction

Yeah, that was the first event I looked for. I never thought about testing for the cursor location... I think this is going to work for me though!  I'll post some samples when I get it working...
Thanks again! |

The issue now seems to be that the rich text box is getting it's content from a file...
| Code: | | $RichTextBox.LoadFile("FileName.rtf") |
Does this affect the .text property? It seems to not be working the same.
UPDATE:
I can return a non-zero number for the elngth of the .Text property after the .LoadFile method executes.
Why would this not work?
| Code: | If Len($rtb.Text) = $rtb.SelectionStart
$ButtonAccept.Enabled = 1
EndIf

$button.enabled is a boolean value.
Therefore to be true set it to -1

It seems that .rtf files must have hidden characters in them because the length of the .Text property is 4812 while I can only get the cursor in the rtb to move to character 4784. Where is how I enabled the button...
| Code: | Function fnAUAKeyDown()
$Loc = $rtbAua.SelectionStart
If $Loc > 4783
$btnAuaAccept.Enabled = 1
EndIf
EndFunction |
Works just like a champ every time...
Thanks for all the input!!! |
