I am learning Qt (in C++) and I have a question regarding the QDateEdit.
I want to be able to type after selecting the text in my QDateEdit. By default you cannot type if you select the whole date. I am sure there is an easy way to do that. How can I change the behaviour to start at the beginning of my QDateEdit instead of doing nothing?
Thanks in advance
In case anyone else has the same problem, the solution is rather simple.
Currently I am using the QDateTimeEdit.
You can override the "keyPressed" method, check for "ctrl+a" and use the "setSelectedSection" method with "sectionAt(0)" which allows the user to start typing at the beginning of the QDateTimeEdit.

Before some code runs, I want to check it is the correct sheet.
I can use the sheet name, but my concern is that if someone changes the sheet name, the code won't run. The sheet index also seems to change if the sheet is moved.
Therefore I want to use something that doesn't change.
I believe the sheet number and sheet ID never change.
So I was hoping to use one of them, but I can't see a way of doing that.
What I want in non-coding language is:
If active sheet number = 4 then run the code or
If active sheet ID = 0123456789 then run the code.
Thanks to JPV's link, I have an answer and learned a few things.
You can't use the sheet number to check if the correct sheet is active.
You can use the getSheetId(), but the return you get is not useable.
To make it useable, you need to add getSheetId().toString().
To do the if statement, I needed two equal signs.
if (SpreadsheetApp.getActiveSheet().getSheetId().toString() == 0123456789) {do this when true}
I've been trying to solve this for days, so I should have come here and asked for help earlier.
The main thing I didn't know was the "toString()" part. It always seems so easy and obvious once I know.
Thank you, JPV.

I'm using this x-editable plugin (https://vitalets.github.io/x-editable/demo-bs3.html) and specifically the "Custom input, several fields" located towards the bottom of the demo.
First, everything is working just fine on the implementation but I'm struggling with how to save the submitted data (see screen shot below further down). I don't know how to reference value[address1] in my sql statement without Lucee thinking its a structure (I hope that makes sense in what I'm trying to say here). When I try to reference the variable reports via writeDump(form.value[address1]), Lucee provides me the following error:
key [value] doesn't exist
How do I reference form fields in the image? Should I change how the data is being submitted perhaps using jQuery's serialize() method?
It was much easier than I thought. I didn't even know you could do this!
local.address1 = form['value[address1]'];
Thanks to the comment made by #Matt-Busche in the SO question, ColdFusion Variable Name with brackets.
I am trying to create a custom lexer based off of JavaScript for QScintilla. I have figured out how to add keywords the the lexer. However, I can not figure out how to alter the way they look when typed in like it does when you type the word function, for example.
I need to figure out how to do this with, for example, the word "fill".
Here's the code I currently have:
QsciLexer *lexer=new QsciLexerJavaScript;
QsciAPIs *api = new QsciAPIs(lexer);
api->add("fill");
api->prepare();
ui->textEdit->setLexer(lexer);
You need to subclass the QsciLexerCustom class. Then you need to make/configure several QsciStyle objects inside that class. The actual syntax highlighting is done in the styleText() function, which you need to override.
You can find detailed explanation on this website:
https://qscintilla.com/
More specifically on this page:

I hope it helps
I often invoke functions from my menu
Many have double entries:
- one for normal substitution
- one for subsitution with confirmation dialog (gc)
p.e.:
vnoreme 20.900 &Edit.Delete\ All\ but\ 1st\ Doubles\ :<C-U>call <SID>DeleteD("'<,'>","confirm-no")<CR>
vnoreme 20.901 &Edit.Delete\ All\ but\ 1st\ Doubles\ (gc)\ :<C-U>call <SID>DeleteD("'<,'>","confirm-yes")<CR>
Is there no better way then the one I use above to indicate a confirmation dialog?
(and to avoid all these double entries)
P.e. when a function invokes an inputdialog box, I would like to have a checkbox added where I can indicate (checking it) to add a dialog confirmation after every substitution, but unfortunately they don't exist and there is no way (as in autohotkey) to create an inputdialog GUI myself.
Well, you could change your Delete() function to ask you, whether you'd like to have each substitution being confirmed. Something like this:
fu! Delete(range)
let confirm = confirm("confirm each change?", "&yes\n&no", 1)
let cmd=printf("%ss/foobar/foobaz/g%s", a:range, confirm ? 'c' : '')
exe cmd
endfu
(this is just an example, you probably want to change at least the search and replace criteria)
Or, if you are using a simple substitution, learn to use the :ex command :promptrepl,
e.g. :promptrepl foobar will open a search/replace dialog where the search field will be set to 'foobar' and you only need to enter the replacement part and hit the buttons you like.
I have been staring at this documentation for 5 hours now. I simply cant connect the steps. If you guys can enlighten me of the stuff.

So my problem are the following:
-at number 5, it asked me to "Set these parameters as follows:", it didnt even mention anything about where? Where to implement the constructor, and why are we using CMFCToolbarComboBoxButton? when it already asked me at step 4 to derive a clas called CFindComboButton. Shouldnt I be making a contstructor for that one instead?
-at number 4(sorry about the non organized numbering of problems), what I did is use the add class (not the class wizard), and then I picked MFC Class. I then enter the supposedly CFindComboButton and Base class as CMFCToolBarComboBoxButton. Did I do something wrong on this one? Do I have to do anything for the ID ID_EDIT_FIND_COMBO?
-When I register the ID_EDIT_FIND_COMBO at the String Table, I dont exactly know what I did. Did I just register an id for future implementation? or is it something else?
-So I cant do step 5, I skipped to step 6. All it ask me is to look for the CreateCombo method athe the override section of properties at CFindComboButton. Well I can only find 3 override. None of them are CreateCombo method. Well from there, you can tell that I'm lost.
I'm a noob at mfc so you might wanna take that in consideration.
Even though your question is a bit jump-led up, let me try and answer so that it works for you.
Create two class - one derived from CComboBox (call it CFindComboBox) and another from CMFCToolBarComboBoxButton (call it CFindComboBoxButton). First class will implement the Combobox that will be shown when you click the drop down button in the toolbar. This drop down button is implemented by CFindComboBoxButton. Hope this is clear.
Now define the constructor for the CFindComboBoxButton as CFindComboBoxButton(UNIT nID, int nImage, DWORD dwStyles) using three parameters as explained below:
Command ID of the button which will be ID_EDIT_FIND_COMBO (or anything you want to define it as). This will get defined in the String Table. Just add a new entry in String Table with ID_EDIT_FIND_COMBO as ID and a placeholder string. Don't omit the string value else the ID will not get defined. The string value can be anything as it wont be used anywhere.
Second parameter will just be a call to CCommandManager::GetCmdImage(ID_EDIT_FIND). This will return the default image used to show the drop down for combobox. In case you want to use your own custom image you can create one and instead pass the ID of that.
Third parameter is the styles you want to use. They are defined at http://msdn.microsoft.com/EN-US/library/7h63bxbe(v=vs.110).aspx but you can use the default value (CBS_DROPDOWNLIST) to start with.
Override the CreateCombo method of CMFCToolBarComboBoxButton and add its implementation to CFindComboBoxButton. In this method create and return a pointer to CFindComboBox (CComboBox derived class).
I hope this clears all the confusion and you should be on your way to have a custom Combobox embedded inside a toolbar.
