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.
Here is the site:

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.
take a look at the VisualStudioDemo Sample:

you can find the CFindComboButton implementation there

I have made a LazyRow that i now want to be able to get the scrollposition from. What i understand Scrollablerow has been deprecated. (correct me if im wrong) The thing is that i cant make a scrollablerow so i thought lets make a lazy one then. but i have no clue how to get scrollposition from the lazyrow. i know how to get index but not position if that eaven exists. here is what i have tried.
val scrollState = rememberScrollState()
LazyRow(scrollState = scrollstate){
}
For LazyScrollers, there are separate LazyStates.
I think there's just one, in fact, i.e. rememberLazyListState()
Pass that as the scroll state to the row and then you can access all kinds of info. For example, you could get the index of the first visible item, as well as its offset. There are direct properties for this stuff in the object returned by the above initialisation. You can also perform some more complex operations using the lazyListState.layoutInfo property that you get.
Also, ScrollableRow may be deprecated as a #Composable, but it is just refactored, a bit. Now, you can use the horozontalScroll() and verticalScroll() Modifiers, both of which accept a scrollState parameter, which expects the same object as the one you've created in the question.
Usually, you'd use LazyScrollers since they're not tough to implement and also are super-performant, but the general idea is that they are used with large datasets whereas non-lazy scrollers are okay for small sized lists and stuff. This is because the lazy ones cache only a small fraction of the entire list, making your UI peformant, which is not something regular scrollers do, and not a problem for small datasets.
They're like equivalents of RecyclerView from the View System
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.
I am using APEX 20.2.0.00.20. apex.region(region_static_id).widget() method should return a jQuery object according to the documentation. I am trying to figure out how to know what the object's properties and methods are, especially when they are not mentioned in the documentation. I tried running apex.region(calendar_region_static_id).widget() to return the object and inspect what properties and methods it has but I got S.fn.init [div#CAL_calendar.fc.ui-widget.fc-ltr, prevObject: S.fn.init(1)] 0: div#CAL_calendar.fc.ui-widget.fc-ltr length: 1 prevObject: S.fn.init [document] __proto__: Object(0)
I did not get the object. I do not know what s.fn.init or the rest of the returned code is?!
I see code like apex.region("calendar_static_id").widget().fullCalendar("getView"), so I assumed I should have gotten the jQuery object which has the "fullCalendar" method and more when I ran apex.region(calendar_region_static_id).widget(), but I have not.
Is this not the right way to inspect a jQuery object's properties and methods?
APEX integrates the FullCalendar widget, but it doesn't duplicate its documentation. Have a look here for a list of the FullCalendar methods and options.
In general, most (interactive) APEX regions are implemented as jQuery UI widgets. That means you can use them like this:
$('selector').widgetName('methodName'); //invokes said method
$('selector').widgetName('methodName', 'param1'); //invokes said method with a parameter
$('selector').widgetName('option', 'optionName'); //gets a specific option
$('selector').widgetName('option', 'optionName', 'newVal'); //sets a specific option
What's more, you can inspect all available options by running:
$('selector').widgetName('option');
And even have a look at the internal object, see all methods, public and otherwise, via:
$('selector').widgetName('instance');
Moreover, via its region interface, APEX offers an even easier way to reach those methods and options, even without having to know a region's widgetName:
// this
$('widgetSelector', 'staticId').widgetName('methodName');
// is equivalent to
apex.region('staticId').widget().widgetName('methodName');
// is quivalent to
apex.region('staticId').call('methodName');
The last way is the shortest and doesn't require knowing the real widget's id or widget name.
All of this helps when dealing with regular APEX widgets, such as the Interactive Grid.
apex.region('emp').call('instance'); //inspects all methods
apex.region('emp').call('option'); //inspects all options
This however does not work on the FullCalendar region, for reasons that are beyond me. It should help you navigate all other APEX regions, but for the FullCalendar you'll have to resort to their API docs.
Hope this helps a bit.
How do you get the state of a Button (clicked or unclicked)? This is a button state and not a question about variables set by the button. How do I tell if an object in a Frame is selected using i.winfo_class() to identify a Radiobutton.
i.e.
for i in a.winfo_children():
if i.winfo_class() == "Radiobutton":
i.get()
Radiobuttons have no get attribute so this will never work, but the logic is the same. I've looked through documentation without success.
The only solution is to get the value of the associated variable and compare it to the value of the radiobutton. If they are the same, that radiobutton is selected.
Found the solution. ttk.Radiobutton has more functionality than the tkinter.Radiobutton.
Please make note there there are major issues with all methods and values dereferences by Radiobuttons even now. Sometimes you get a pointer, sometimes you get a string and need to dereference yourself. This makes Radiobuttons a more difficult Widget to deal with than most of the others I've been working with. There are many documents on this and they are fixing this, but it is something to note.
For my purposes, tkinter.Radiobutton has no instate which means there is no simple way to check if it is clicked. I was getting pointer after pointer and dereferencing was far too tedious and complex to code for a dynamic gui.
The code I've ended up with is as follows:
for i in a.winfo_children():
if i.winfo_class() == "TRadiobutton" and i.instate(['selected']) is True:
return i.cget('value')
Also make note that TRadioButton string is used instead of RadioButton, the object type returned is not the same between ttk and tkinter implementations of Radiobutton.
I would like to ask about this controller.
In past versions like 1.5 I could find it in admin/tabs and add additional functions.
In 1.6 version I can`t find any admin classes files. So I should edit controllers/admin/AdminOrdersController yes?
elseif(isset($_POST['submitInvoice'])){
if ($this->tabAccess['edit'] === '1')
{
mysql_query('UPDATE `'._DB_REFIX_.'orders` SET `invoice_number` = \''.$_POST['invoice_number'].'\',`order_date` = \''.$_POST['order_date'].'\', `changed_invoice`=1, `manager`=\''.$cookie->firstname.' '.$cookie->lastname.'\', `changedStatus`= \''.$_POST['changedStatus'].'\' WHERE `id_order` = '.$_GET['id_order']);
}
}
I add this code to update some values like invoice number or order date. But I can`t to update this. Got same date and number. Is it bad method to update or what?
You should always use modules and hooks to modify PrestaShop logic if possible
If you need to override a function and there is nor suitable hook, you should use overrides: override/controllers/admin/AdminOrderController.php. Contents of this files should look like : AdminOrderController extends AdminOrderControllerCore. If you're unsure what I mean, you should try searching for any override classes in overide folder.
You code is extremely unsafe. You should at least use Db::getInstance()->execute($sql);.
You code might not be working because you are writing you values somewhere in the middle of a function, and the Order is an object, which mean that possibly the Order object is saved after you wrote you values to database. When the order object is saved, it overwrites your values
