How to clear a combo-box selected values when clicking on a 'Clear' button? When the time of clicking clear button, it needs to set it as default.
I wrote it as;
DO:
ASSIGN
coCombo-2:SCREEN-VALUE IN FRAME {&FRAME-NAME} = "".
coCombo-3:SCREEN-VALUE IN FRAME {&FRAME-NAME} = "".
END.
"But this is not working."
You need to assign a space instead of an empty string
DO:
ASSIGN
coCombo-2:SCREEN-VALUE IN FRAME {&FRAME-NAME} = " ".
coCombo-3:SCREEN-VALUE IN FRAME {&FRAME-NAME} = " ".
END.

I'm trying to get the variable that's entered in an entry widget on the Return key pressed event, but struggling a bit. What I have tried has always produced a blank result.
This code may look messy and hap-hazard, but it's only going to be a template that I'll be using on a current project!
I've tried that many things to get it to work, I can't remember what I have tried!
from collections import OrderedDict
try:
import tkinter as tk
except:
import Tkinter as tk
root = tk.Tk()
labelLIST = OrderedDict([
('Temp ID', 'tempID'),
('PO Number', "poNumber"),
('Reference', "reference"),
('Cut/Sample Date', "csDate"),
('Cut Number', "cut")
])
i = 0
e_loops = len(labelLIST)
print (e_loops)
def bval1(event=None):
for i in range(e_loops):
print (entries[i].get())
entries[0].delete(0, tk.END)
entries[0].insert(0, 'DISABLED')
entries[0].configure(state='disabled')
def bval2():
entries[0].configure(state='normal')
for i in range(e_loops):
entries[i].delete(0, tk.END)
entries[0].focus()
def onClick(event):
ent = event.widget # event.widget is the widget that called the event
print(ent.cget("text")) # Print the text for the selected button
event.widget.tk_focusNext().focus()
def enterEV(event):
# print(entries[].get())
event.widget.tk_focusNext().focus()
entries = []
for key, value in labelLIST.items():
label = tk.Label(root, text=key)
label.grid(row=i, column=0, sticky="ew", padx=1, pady=1)
entry = tk.Entry(root, width=10)
entry.grid(row=i, column=1, sticky="ew", padx=5, pady=5)
if value == "cut":
entry.bind('<Return>', bval1)
else:
# entry.bind('<Return>', enterEV)
entry.bind('<Return>', onClick)
entries.append(entry)
i = i+1
button = tk.Button(root, text="Submit", command=bval1)
button.grid(row=0, column=2, columnspan=9, sticky="ew")
button = tk.Button(root, text="Clear", command=bval2)
button.grid(row=1, column=2, columnspan=9, sticky="ew")
entries[0].focus()
tk.mainloop()
When enter/return is pressed, I want the value that is the entry box to be printed to terminal via the onClick event. But the output is always empty.
def onClick(event):
ent = event.widget # event.widget is the widget that called the event
print(ent.cget("text")) # Print the text for the selected button
event.widget.tk_focusNext().focus()
You don't use the text attribute to get the value in an Entry widget. Using cget("text") returns the value for the textvariable attribute. Since you haven't set that attribute, it will always be the empty string.
Instead, you need to call the get method:
print(ent.get())
this is how the data is displayed but i want
Rhugveda desai -> flowers,Sarees,Prasad
In my application i need to use group by clause . But i am getting a syntax error.Also, What should i do if i want quantity column to be multiplied by amount to get the total? My tables are inkind and inkind_items, where inkind.id is foreign key in inkind_items table as inkind_id.
SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #11
of SELECT list is not in GROUP BY clause and contains nonaggregated
column
my inkind_items tabel is inkind_items
my inkind table is inkind
My query is:
$inkinds = DB::table('inkind')
->join('inkind_items', 'inkind.id', '=', 'inkind_items.inkind_id')
->select('inkind.*', 'inkind_items.*')
->groupBy('inkind_items.inkind_id')
->get();
Try using group_concat()
$inkinds = DB::table('inkind')
->join('inkind_items', 'inkind.id', '=', 'inkind_items.inkind_id')
->select('inkind.*', DB::raw('group_concat(inkind_items.name) as items'))
->groupBy('inkind_items.inkind_id')
->get();
Here I'm assuming inkind have field name and inkind_items has fields items.
You can use Laravel collection methods for that.
Just call:
$inkinds->groupBy('inkind_id');
after ->get(). Considering that inkind_id is unique column for both tables
Hi. You asked another question earlier today (about displaying an input when a particular checkbox is checked) but deleted it before I submitted my answer, so I thought I would paste the answer here instead:
Just to get you started, here is an explanation of how to use
addEventListener and createElement to achieve your desired result.
If any part of it is still unclear after studying the code and the
accompanying comments, please search for the name of the still-unclear function on
MDN.
(For example, https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementsByClassName.)
// Sets `box1` to refer to the first element on the page with the class "box".
const box1 = document.getElementsByClassName("box")[0];
// Sets `container` to be the element whose id attribute has the value "container".
// (This is where our new input element, inside a new label element, will be added.)
const container = document.getElementById("container");
// Begins listening for clicks. From now on, whenever the user clicks anywhere
// on the page, our listener will call the `noticeClick` function.
document.addEventListener("click", noticeClick);
function noticeClick(event){
// Because this function's name is the second argument in
// the call to `document.addEventListener`, above, it is
// automatically called every time a 'click' event happens on the
// page (and it automatically receives that event as an argument.)
// The "target" of the event is whatever the user clicked on.
// So we set the variable `targ` to refer to this target, and we check whether:
// 1) the clicked target is our checkbox,
// 2) this click caused the checkbox to gain the "checked" attribute, and
// 3) we have not already given the checkbox the "added" class
const targ = event.target;
if(targ.id == "box1" && targ.checked && !targ.classList.contains("added")){
// If all three conditions are met, we...
// ...set two variables, `label` and `val`
const label = event.target.id;
const val = event.target.value;
// ...call the `createInput` function, passing these variables as its two arguments
createInput(label, val);
// ...give the checkbox the "added" class (so we can avoid accidentally adding it again)
targ.classList.add("added");
}
}
function createInput(newLabel, newValue){
// When the user has checked our checkbox, the `noticeClick` function
// will call this function, which receives two arguments (which we can
// see, by examining the `noticeClick` function, are two strings: the
// `id` attribute of box1 and the `value` attribute of box1.)
// We use `document.creatElement` to create an `input` element and a
// `label` element, and `document.createTextNode` to set some text
// to be used in the label (using the "newLabel" argument.)
const myInput = document.createElement("input");
const myLabel = document.createElement("label");
const myLabelText = document.createTextNode(newLabel + " ");
// We set our new `input` element's value using the "newValue" argument.
myInput.value = newValue;
// We use `appendChild` to put both the text and the input element
// inside the label, and to put the label inside `container`.
myLabel.appendChild(myLabelText);
myLabel.appendChild(myInput);
container.appendChild(myLabel);
}
// This process can be applied to multiple checkboxes on the same page
// by adding a loop inside the `noticeClick` function, where the string
// "box1" should be replaced with a variable that can refer to the id of a
// different checkbox's `id` for each iteration of the loop.
<label>
<input type="checkbox" id="box1" class="box" value="value1" />
Label for box1
</label>
<hr />
<div id="container"></div>
I had to automate scenario where i get First Name and email address , which i had stored then i need to assert that value with drop down box that its not present.
Here is HTML code for my Page
<select id="Customer" name="Customer" class="valid">
<option value="raj777#gmail.com">123123123 (raj777#gmail.com)</option>
</select>
It contained multiple entries ,
I need to verify that my given text does not exist in it.
I tried this but it does not works
assertNotEquals(fname+" "+em, driver.findElement(By.xpath("//*[#id='Customer']")).getText());
Thanks In Advance !!!
Follow the below process:
Get the text of each element in the dropdown ('option' elements)
Strote the values in a list or array of string.
See the list or array contains your Name & mail id value.
or if u want to assert only, then in for-each loop of the array or list:
Add t
he assert statement in try-catch block.
In catch block, each time execution comes to this block, increase an integer.
After the fr-each loop, check the integer value is equal to yor list or array size.
Code sample for the first scenario:
driver.findElement(By.cssSelector(".trb_outfit_sponsorship_logo_img"))
.click();
System.out.println(dri.findElement(
By.cssSelector(".trb_outfit_sponsorship_logo_img")).getSize());
List<WebElement> dropDownValues = dri.findElements(By
.xpath("//select[#id='Customer']"));
ArrayList<String> dropDownValuesasText = null;
for (WebElement eachValue : dropDownValues) {
dropDownValuesasText.add(eachValue.getText());
}
// boolean result = dropDownValuesasText.contains("Your FirstName & Email value");
//It will pass if your value is present in drop down
assertNotEquals(dropDownValuesasText.contains("Your FirstName & Email value"), true);
My code has 2 parts. First part is an automatic file opening programmed like this :
fichierref = 'H:\MATLAB\Archive_08112012';
files = dir(fullfile(fichierref, '*.txt'));
numberOfFiles = numel(files);
delimiterIn = ' ';
headerlinesIn = 11;
for d = 1:numberOfFiles
filenames(d) = cellstr(files(d).name);
end
for i=1:numberOfFiles
data = importdata(fullfile(fichierref,filenames{i}),delimiterIn,headerlinesIn);
end
Later on, I want the user to select his files for analysis. There's a problem with this though. I typed the lines as follow :
reference = warndlg('Choose the files from which you want to know the magnetic field');
uiwait(reference);
filenames = uigetfile('./*.txt','MultiSelect', 'on');
numberOfFiles = numel(filenames);
delimiterIn = ' ';
headerlinesIn = 11;
It's giving me the following error, after I press OK on the prompt:
Cell contents reference from a non-cell array object.
Error in FreqVSChampB_no_spec (line 149)
data=importdata(filenames{1},delimiterIn,headerlinesIn);
I didn't get the chance to select any text document. Anyone has an idea why it's doing that?
uigetfile is a bit of an annoying when used with `MultiSelect': when you select multiple files the output is returned as a cell array (of strings). However, when only one file is selected the output is of type string (not a cell array with a single cell, as one would have expected).
So, in order to fix this:
filenames = uigetfile('./*.txt','MultiSelect', 'on');
if ~iscell(filenames) && ischar( a )
filenames = {filenames}; % force it to be a cell array of strings
end
% continue your code here treating filenames as cell array of strings.
EDIT:
As pointed out by #Sam one MUST verify that the user did not press 'cancel' on the UI (by checking that filenames is a string).
I have an UltraOptionSet control that is unbound. Once a value has been selected, how can I clear the selected value? I want the net effect of all options in the UltraOptionSet control to be unselected.
I tried setting the Value property to null and DBNull.Value but neither cleared the selected option.
Just set
optionSet.CheckedIndex = -1;
this will clear the current checked item and nothing else will be set.
Set the Value to Null rather than DBNull.Value and it will clear the selection. You can also set the value to an empty string.
There are a few other ways as well and I believe this is all of the possible ways to clear the value for an unbound UltraOptionSet:
this.ultraOptionSet1.Value = null;
this.ultraOptionSet1.Value = "";
this.ultraOptionSet1.CheckedIndex = -1;
this.ultraOptionSet1.CheckedItem = null;
this.ultraOptionSet1.ResetCheckedIndex();
