not sure if I've come to the right place or not. Any help is appreciated.
I am creating a form that will post certain air quality test results on a building. Users will insert particular numbers in the form (e.g., concentration of certain gases, etc.). If number meets acceptable standards (e.g., below acceptable maximum), then I would like a check box to turn on that says the building meets the safety standards.
let A be air quality value
let B be maximum accepted value
let C be checkbox indicating pass
So, if A is less than B, then C is ON (pass) but if A is greater than B, C is OFF (fail)
Ideally, C will be a graphic of a green check mark or a red ex.
thx
You'll need to set up a file with your field and 4 "buttons" set to read-only which are really just holders for your graphics. One is the visible button that has its image replaced by the code, three of them are hidden, the check, the X, and a clear one for when the form is reset. Then add the following code to the Custom Format script of the field. The code will use the value of the field to swap the button icons. The value of 50 is arbitrary. Set it to the number you need.
if (event.value != "") {
if (event.value <= 50) {
this.getField("graphic").buttonSetIcon(this.getField("passed").buttonGetIcon());
}
else {
this.getField("graphic").buttonSetIcon(this.getField("failed").buttonGetIcon());
}
}
else {
this.getField("graphic").buttonSetIcon(this.getField("clear").buttonGetIcon());
}
You can download a working example from here.

I've created multiple text fields where each text field accepts only 1 character and then moves to the next box. I would like to check users answer when all the text fields are filled but I'm a bit confused as to how to do so.
My first approach was to create an answer String and every time textFieldDidChange is called I add to the String the textfield.text but how can I know when all the boxes been filled and call the checkAnswer function another issue is that if the user decides to fill the boxes in a different order then when I compare the user answer to the correct answer it obviously comes incorrect as the order is different.
[here's a pic of the boxes every game round it generates a different number of boxes depending on the answer
If you know how many number of textFields you have then, you can add a property observer to yourAnswerString and as soon as the value of yourAnswerString becomes equal to numberOfTextFields, it will call the check Answer function automatically.
var yourAnswerString = "" {
didSet {
if yourAnswerString.count == numberOfTextFields {
self.checkAnswer()
}
}
}
I had an editable pdf with checkbox, after selection i flatten that pdf. from that flatten pdf i need to read the checkbox selection which is looks like crossmark(X), is there any possibility to read that checkbox selection.
When you flatten a PDF, you take away all interactivity. If you have a check box field in an interactive form, and you flatten that form, the check box field is gone. That is the concept of flattening.
What happens in practice?
A check box field has two appearances. One appearance is Off. This appearance can be a path such as a simple square defined as a rectangle. Another appearance can have any name On, Yes, 1 or whatever is defined in the original form. The corresponding appearance can be the same square as the Off appearance with two extra lines that look like a cross, or the square with a character that looks like a check mark, or whatever was defined in the original form.
When you flatten the form, you throw away the name of the check box field, you throw away the widget annotation that corresponds with the field, and you throw away one appearance state (depending on the value of the check box field). The only thing that is left, is one of the two appearances.
If you no longer have the original form, you have no clue as to what this appearance could look like, hence you have no idea what to look for, nor where to look for a specific appearance.
You say that the appearance looks like a cross mark in your case, but whoever reads this question has no idea if this cross mark is a path that was constructed in graphics state, or a glyph that was added in text state.
Long story short: if you flatten first and then expect to be able to read a field value, your design is seriously flawed.
You have to ask yourself: why do I need to flatten the form? Maybe it's sufficient to make the fields read-only. If that's not sufficient, why don't you add an attachment to the PDF that contains the original field values? There are many different ways to work around your problem.
I want to validate that user cannot change spinner value manually by typing in text box of spinner.
For example a field sales multiple = x which I fetched from server not fix.
and displays a spinner field with limitation of like bellow
spinner.setMinValue = x
spinner.setIncrement = x
spinner.setValue = x
so user forcefully select a value which is multiple with x. e.g. if x=3 the user have to enter 3,6,9... and so on.
So here my issue is if I type a 2 in spinner field text box. GXT widget accept that value.
Posible solutions:
Is there any predefined properties of spinnerfield that i forget to set it?
Is there any predefined validator for this?
Can I set text box of spinner field read only by css so user cannot focus on text box but still change a value.
If none of above how to achieve manually?
i've searched a bit in the different classes and I don't see either a precise method which would set what you want.
Don't know about one, and even with one, a validator doesn't change the value in the input field, but maybe it's enough for your needs.
You can disable the text input by calling setEditable(boolean) on the spinnerfield (testSpinner.setEditable(false);)
Maybe you could search around the IntegerPropertyEditor, I haven't tried but as long as a new Spinner is like this:
SpinnerField<Integer> testSpinner = new SpinnerField<Integer>(new NumberPropertyEditor.IntegerPropertyEditor());
you can seen that there is another Constructor for IntegerPropertyEditor, which takes a "NumberFormat" param, but there is no NumberFormart() constructor, so I'm not sure about how you create your own one, but that could be an idea (to format numbers in the input to be a multiple of the increment).
The last option would be that Sencha forgot this possibility and that you should report this as a "bug" on the forum ?
Hope to have helped a bit, good luck :).
I have a few text boxes which have to be filled with numeric values from 0 to 100. Below them there is another text box which stands for a total (the sum of the values from the text boxes above). How can I update the sum text box while typing in any of the other text boxes above?
If you are happy that the sum box updates after a box is updated (enter, tab or such like is pressed), then this can be done without any code. First, you will need to set the format of the textboxes to be summed to numeric, then the control source of the sum box becomes:
=Nz([text0],0)+Nz([text2],0)+Nz([text4],0)+Nz([text6],0)+Nz([text8],0) ...
Note the use of Nz, it may be possible to eliminate this by setting the default value property of the various textboxes to be summed.
A large set of controls that need to be summed in this way is often an indication of an error in the design of the database. You would normally expect this kind of thing to be a separate recordset, which could more easily be summed.
I know this is old, but Google didn't come up with much for this topic and this thread didn't really help either. I was able to figure out a very easy way to do this, so hopefully anyone else looking for this will find this helpful.
My need was for actual text as opposed to numbers, but the same applies.
To do what the OP is asking for you'll need at least 3 textboxes. 1 is the textbox you want to have updated each time you type, 2 is the textbox you will be typing in, and 3 is a hidden textbox.
Set textbox 1 to reference the value of the hidden textbox 3 in its control source:
="something in my textbox " & [textbox3]
In the OnChange event of textbox 2 right a line that will set the value of the hidden textbox 3 to the Text property of textbox 2 that you are typing in:
Private Sub textbox2_Change()
Me.textbox3.Value = Me.textbox2.Text
End Sub
Each time the value of the hidden textbox 3 gets updated, the calculation/reference in the displayed textbox 1 will be updated. No need to save caret locations or anything else mentioned in this post.
I was able to do this in Access 2007 by using the On Lost Focus event of the text box.
Just put something like this on the On Lost focus event of each text box that you want to be added , just make sure to set the default value of each text box to 0.
Me.Totals.Value = Me.Text1.Value + Me.Text2.Value + etc..
The moment you click on the next text box or anywhere as long as it loses focus, your sum will already be on the Totals box. You may add as many text boxes as you like, just include them in the code.
This is problematic due to the asinine requirement in Access that you have to set focus to text areas before you can get their value. I would recommend you change your design so that the text field is updated in response to a button click instead of on change.
If you want to go the update-on-change route, you would attach change events to each of the addend text fields. The event handlers would need to save the caret position/selection length, update the sum in the output text field, and restore the caret position. You need to save/restore the caret position because this is lost when the focus changes.
Here's an example for two text fields (txt1 and txt2). The output field is named txtOutput.
Private Sub txt1_Change()
Dim caret_position As Variant
caret_position = Array(txt1.SelStart, txt1.SelLength)
UpdateSum
txt1.SetFocus
txt1.SelStart = caret_position(0)
txt1.SelLength = caret_position(1)
End Sub
Private Sub txt2_Change()
Dim caret_position As Variant
caret_position = Array(txt2.SelStart, txt2.SelLength)
UpdateSum
txt2.SetFocus
txt2.SelStart = caret_position(0)
txt2.SelLength = caret_position(1)
End Sub
Private Sub UpdateSum()
Dim sum As Variant
sum = CDec(0)
txt1.SetFocus
If IsNumeric(txt1.Text) Then
sum = sum + CDec(txt1.Text)
End If
txt2.SetFocus
If IsNumeric(txt2.Text) Then
sum = sum + CDec(txt2.Text)
End If
txtOutput.SetFocus
txtOutput.Text = sum
End Sub
When using an aggregate control in some reports you would prefer to see a blank field instead of 0. There does not appear to be a way to do this automatically. Does anyone have a way that this can be done. Note, you want to maintain the '0' value for the field in cases when you export, but you want to show a blank when rendering to PDF or HTML.
There are a number of ways to solve this. The two primary are to use either visibility rules or highlights to create conditional formatting. The visibility is particularly attractive since it is easy to only apply the format rules to particular types of output (e.g. HTML).
For this particular case, there are two problems with these approaches. First, I want a general solutions where I don't have to specify the text color. In other words, when the condition is true (value of 0) then I want my text color to match the background color. In that way if someone changes the backgroundColor for the control, the code still works.
The other issue is that in this case I am using dynamic column binding which does not support value lookup.
The solution that I created was to add a JavaScript function called hideMe as shown below.
function hideText (dataControl){
if (dataControl.getValue() == 0) {
var color = dataControl.getStyle().getBackgroundColor();
var parentItem = dataControl.getParent();
do {
if (color == null && parentItem != null) {
color = parentItem.getStyle().getBackgroundColor();
parentItem = parentItem.getParent();
} else {
break;
}
} while (color == null);
dataControl.getStyle().color = color;
}
}
Once this function has been added to the report (in my case an included javascript file) I just call it from the OnCreate method of the control.
hideText(this);
This can also be done using Java Event Handlers but this method seems to be easier.
Just an FYI, after working with this for a while longer, I have found that it is just easier to use Visibility rules. The one big advantage is that you can easily configure different visibility for different output formats. So for PDF it may be best to use blanks, but for Excel you may want the 0 values.
