I am trying to set the toolbar item dynamically. So far I have a back button that resets the toolbar title to 'start' if the user chooses to go back.
But the following code won't work:
menuList.on('itemtap', function(dataView, index, item, e){
viewport.dockedItems.items[0].setTitle('{title}');
});
It tries to use a variable called 'title' out of my data store array. This works great for providing text to my Ext.List items. But the above code sets the toolbar title to the string '{title}' without even thinking of it being a variable.
Can you help me out?
List's use templates so items within curley braces get evaluated... you'll need to pass a reference to a variable without quotes. You haven't provided enough code for me to tell you where that information would be. If you already have a variable in scope called title that you put the data into then you can just reamove the '{ and }' ... otherwise you'll need to get the data you need from your store through some means, like Ext.StoreMgr or [appname].stores
Two things. 1) You will really want to get used to digging into the ST source code. In this case, if you look at the code for "setTitle", you will see that its argument is interpreted as straight HTML, not a template. So you can't use curly bracket syntax here. 2) Note that the type of the "item" argument to the event handler is an Element (i.e. ST's representation of the DOM object, not the selected datastore object. So that's not going to help you. However, the "index" arg gives you an easy way to get the appropriate object from the store. i.e.
[appname].stores.pages.getAt(index).title
I really don't know why, but it works if you put up to variables: One for the record and one for the value inside that record. There is a detailed explanation in the sencha.com-forum

Let's say I have a type of object in my game called oCharacter. All characters must have names, so I want to provide one when I construct the object. I can do that by using the _variables argument of instance_create_layer:
instance_create_layer(0, 0, "Instances", oCharacter, { name: "George" });
I could even make sure that I don't forget to do this by making a "constructor" function for characters and only instantiating them using that:
function character_create(_x, _y, _name) {
return instance_create_layer(_x, _y, "Instances", oCharacter, { name: _name });
}
But this approach has two problems.
The first is that I or another developer might forget about this convention and instantiate a character directly using instance_create_layer, forgetting to pass a name and setting up a runtime error further down the road.
The second (related) issue is that Feather doesn't know about this convention, so my Feather window is full of error messages about references to instance variables that aren't declared in the Create event - but I don't see how I can declare these variables in the Create event, as I'm expecting their value to be provided by the creator.
Is there some way of doing this that addresses these issues?
The first problem is just about setting rules about the code conventions within your team, if your team does not know about these conventions you want them to follow, then you should tell it them in a meeting.
For the second problem: Maybe you could create an empty/nullable variable in the Create Event? I'm afraid I'm not familiar with Feather
Personally I would do two things for this.
Create development standards for the team and put them in something like a Word document, wiki page, onenote, whatever makes the most sense for your team.
I would use a function to create the instance of the object (like you're doing there), and have some simple validation checks inside of the create event itself that will cancel it's creation (something like a guard clause) and output a debug message with a reminder.
It's not the most elegant solution but that should do the trick (assuming you haven't found something else by now haha)
In my current project in Access VBA, I created a window which works like a console and now I am trying to add a possibility to display any public variable. It should work like:
Show_var [variable_name]
So it should be like in the direct window where i can type:
? pVar.variable_A
I found out that using
Application.VBE.ActiveVBProject.VBComponents(11).CodeModule.CountOfLines
I can display the number of lines within a module or form so I thought perhaps I could somehow find the variables there, cycle through them and when the correct one is found, its value can be shown. OFC I could make a Select Case Statement where all variables are included but that is not the way I want to do it because it is complicated and must be changed every time update my public variable list.
There are so many problems that I think you are out of luck. Let me just list some of them:
There is no way to get a list of all variables - that would mean you would need access to the internal symbol table.
As a consequence, you would have to read the code (CodeModule lets you read the code of a module), and write an own parser to fetch all declarations (hopefully you use Option Explicit)
AFAIK, the is no method that can access the content of a variable via it's name.
Even if there would be any such method: What would you do with different data types, arrays and especially with objects.
If a user runs into problems, often it is a runtime error. If you don't handle that errors with some kind of error handler, the only option if a user cannot enter the debugger is to press "End" - which would destroy the content of all variables.
You have to deal with scope of variables, you can have several variables with the same name and you will likely have lots of variables that are out of scope in the moment you want to dump them.
I am trying to assign the value of this stucture path to a fieldsymbol, but this path does not work because it has a table in it's path.
But with in the debugger this value of this path is shown correctly.
Is there a way to dynamically assign a component of a table line to a fieldsymbol, by passing one path?
If not then I will just read the table line and then use the path to get the wanted value.
ls_struct (Struct)
- SUPPLYCHAINTRADETRANSACTION (Struct)
- INCL_SUPP_CHAIN_ITEM (Table)
- ASSOCIATEDDOCUMENTLINEDOCUMENT (Element)
i_component_path = |IG_DDIC-SUPPLYCHAINTRADETRANSACTION-INCL_SUPP_CHAIN_ITEM[1]-ASSOCIATEDDOCUMENTLINEDOCUMENT|.
ASSIGN (i_component_path) TO FIELD-SYMBOL(<lg_value>).
IF <lg_value> IS NOT ASSIGNED.
return.
ENDIF.
<lg_value> won't be assigned
Solution by Sandra Rossi
The debugger has its own syntax and own logic, it doesn't apply the ASSIGN algorithm at all. With ABAP source code, you have to use ASSIGN twice, the first one to reach the internal table, then you select the first line, and the second one to reach the component of the line.
The debugger works completely differently, the debugger code works only in debug mode, you can't call the code from the debugger (i.e. if you call it, the kernel code used by the debugger will fail). No, there's no "abappath". There are the XSL transformation objects (xpath), but it's slow for what you ask.
Thank you very much
This seems to be a rather unexpected limitation of the ASSIGN statement. Probably worth a ticket to SAP's ABAP language group to clarify whether it's even a bug.
While this works:
ASSIGN data-some_table[ 1 ]-some_field TO FIELD-SYMBOL(<lv_source>).
the same expressed as a string doesn't:
ASSIGN (`data-some_table[ 1 ]-some_field`) TO FIELD-SYMBOL(<lv_source>).
Alternative 1 for (name) of the ABAP keyword documentation for the ASSIGN statement says that "[t]he name in name is structured in the same way as if specified directly".
However, this declaration is immediately followed by "the content of name must be the name of a data object which may contain offsets and lengths, structure component selectors, and component selectors for assigning structured data objects and attributes in classes or objects", a list that does not include the table expressions we would need here.
I'm using Vue-Material. It doesn't support the passing of objects inside the value of the option.
This is the link to Github issue about it with some advice how to make this work.
What I can not do is implement it to the structure of my object.
I want to have the first select with options of value2 of all items.
And then in the second select, I want to have all values1 of selected value2.
Here what I have so far
I hope that someone can help me with it.
What works without Vue Material:
I just bind to the value of option the selected object. And when #change on select reassign in my data something like this.innerGroup = this.selectedGroup.value1 and then just loop over this.innerGroup in v-for
I'm trying to build a Python Unit Test File Template in PyCharm. The overall result I want to achieve is:
A user creates a new file with my template, say "widget_builder.py"
Inside the template I want to create the class name by taking the file name "widget_builder" and turning it into "WidgetBuilderTests"
It looks like I need to use a Live Template to manipulate the file template variable $FILE_NAME$?
How can I create a Live Template that given a passed in variable (in this case $FILE_NAME$), applies both the underscoresToCamelCase and capitalize functions to it?
If I declare the Template text as:
$CLASS_NAME$
...and then edit variables, how can I reference a passed in variable of '$FILE_NAME$'?
I'd imagine it to look something like this, but I just can't get it to work:
I'm sure there must be a way to do this, but I just can't quite wrap my head round it.
Is this possible? Thanks!
EDIT
I've got a bit further. If I define the template as this:
If I then use it, this happens:
So the end result of $CLASS_NAME$ (WidgetBuilder) on the left is what I want, but I don't want $FILE_NAME$ (widget_builder) to be there once I hit return.
So your problem here is that $FILE_NAME$ is not a native variable in the live templates, merely an arbitrary name. What you actually want to be using is another function: fileNameWithoutExtension().
So your template would look something like:
