I want to perform something like the one below:
display a dataframe in RGTK2 window, with scrollbar on the right
user can select the specific row in the dataframe by clicking on it, and I can "get" which row the user has actually clicked
I wonder if this can be done using RGtk2. Thanks.
Yes, of course. Have a look at: https://github.com/jverzani/gWidgets2RGtk2/blob/master/R/gtable.R . You can pull out most of the first request in the initialize method and the second in the set_selected and get_selected methods. The task is made much easier (and faster!) by Michael Lawrence's rGtkDataFrame constructor to turn data frames into models that RGtk2's views can use quite easier.

I have an issue that is quite complex to solve using Octoparse. Let's say we have a value extracted from one page, let's call that value as ID. Then we have a pop-up window that shows up when you click on a button that is on a different page. The pop-up window contains a table with different IDs in one column and links in another column. I want Octoparse to compare unique ID from the very first page with different IDs in the popup window, find the match (IDs are all unique, but only one matches), and extract the link right next to it (in the second column). Basically, it sounds like using a vlooukup function in Excel. Is this possible? Can you help me out with that, please?
Maybe there's a way to solve this issue using XPath, I don't know.
I couldn't solve this issue using Octoparse.
Is there a way to extract a table from a web page in Automation Anywhere after taking certain steps using web recorder. The table does not appear directly, it appears after clicking few controls after launching the URL.
The table that I want to extract is coming after loggin in to the website and filtering using a control for search criteria.
I used web recorder to login and putting the desired search criteria in a text field and I want to extract the table now. When I use web recorder, it launches the URL again and takes me back to the login page which I dont want. I want the bot to stay on the page. Pls help.
Also, what is the significance of session name of an extracted table?
If you clicked on Advanced View, you will find at Step 5 : to run this command using an existing IE window. Try to write the URL of the page with the table and not the one of the login page.
The extracted table is to be used using variable $Table Column(Index)$ with index being the column number or column name
you can export directly using object cloning and in the selection criteria export to csv file. But we need to click on html inner text also in search criteria
An old question, but my experience has been the Extract Data/Table commands are rather poor. Not only do they only work in IE, you cannot call them as commands, they have to be called via a web recording.
Instead, I've found it much more useful to object clone the initial element, grab the DOMXPath, and variablize that. Then throw it into a loop while command and set the condition on finding at least one element (of the elements for the table you are trying to build). You can grab all sorts of useful info in the object clone command and then right that to a variable/table.
For example
//div[#id='updatable-standings']/div[1]/div[1]/div[2]/div[1]/table[1]/tbody[1]/tr[3]/td[2]/div[1]/span[2]
//div[#id='updatable-standings']/div[1]/div[1]/div[2]/div[1]/table[1]/tbody[1]/tr[4]/td[2]/div[1]/span[2]
I can create a incremental variable for {tr[3]} and call it $vTeamLoop$ and change my DOMXPath value in the Object Clone to be
//div[#id='updatable-standings']/div[1]/div[1]/div[2]/div[1]/table[1]/tbody[1]/tr[$vTeamLoop$]/td[2]/div[1]/span[2]
Ultimately, it is more steps than the Data/Table Extract command, but it is far less limited in scope.
Hope that helps.

We have a hierarchical watch app.
The root controller is a table of menu items. That list of items is controlled by a server. The data is retrieved and stored in core data. The menu is populated the first time going into the app.
But I want this table to stay current. My thought was to add code to willActivate to check if there was changes, and reload the table. In my reload logic I call the same function I called the first time, which sets the menuTable.setNumberOfRows and creates each row. Looking at what I'm putting in the logs, it is going through this logic with a different count of rows and new labels. But the app on the watch shows the table with the old data.
How can I get this table to reload with the new information?
I've had this problem too and as rmp says, it still seems to be a bug in watchOS 1.0.1. The problem appears when you try to reload your tableView after run willActivate() and nothing will happen.
In my case, I reload the tableView after receive a reply from a delegate and then I reload all the content just if it's necessary. To achieve this, I remove all rows from a NSIndexSet and load again.
if isNecessary {
self.table.removeRowsAtIndexes(NSIndexSet(indexesInRange: NSMakeRange(0, maxItems)))
isNecessary = false
}
I've tried a lot of tricks but none has worked for me:
Force to reload rows by table.setNumberOfRows(0, withRowType: "data")
Setting parameters to empty text before assign new values
One thing you could do is to hide tableView before removing rows, and avoid the remove animation.
It is a bug in WatchKit. Seems like Apple doesn't handle the repetitive interface object correctly.
The general principle here is: Only insert or remove necessary rows after a table is created. Do not reload the whole table like what we usually do in iOS. It just doesn't work (or trigger the bug).
So specifically, you have to:
Do this in willActivated method. This is correct.
If this is the first load, before the table is even created, do what you are now doing – load all table rows.
For all following times, don't reload the table, fetch the new data and check the desired number of rows.
Compare with the current number of rows in the table, insert to or remove from the bottom of the existing table.
Now simply re-assign the new data to all existing rows. Again, do not reload.
It should work if you follow the above steps.
I have found what works best given the current state of watchkit is to remove all rows then re-populate the table.
Try something like this:
- (void)loadTableData{
//clear the table
[mainTableView setNumberOfRows:0 withRowType:#"myTableRow"];
//set the row count again
[mainTableView setNumberOfRows:numberOfRows withRowType:#"myTableRow"];
//populate table
}
Its pretty simple. As Apple hasn't provided any method to reload the data.
You can still achieve that by simply populating the rows for the tableview.
Below is the sample code:
for index in 0..<tracksTableView.numberOfRows {
if let controller = tracksTableView.rowController(at: index) as? EditPlaylistRowController {
controller.playingTrackId = self.playingTrackID
controller.sharedTrack = trackItems[index]
}
}
Use it whenever you want to refresh the data.
NOTE:
You can still make some conditional statements inside the row controller class.
Happy to help :)
My project is in Asp.Net Webforms using C#.
On one of my web pages, I want to have two tables. One is going to be a summary table and the other a more detailed breakdown of the summary. When the user clicks on one of the rows of the summary table, I want the corresponding breakdown rows to appear in the breakdown table.
These tables can have anything between 60 and about 500 rows.
I have thought of two possible ways of doing this and I'm not sure which is best, or if there is another, better way of implementing this:
1) When a user clicks on one of the rows in the first table, a postback event happens, and the data for the second table is loaded from the code behind.
2) When the webpage is loaded for the first time, both tables are filled with all of the possible data, but all of the rows in the second table have the "display: none;" CSS attribute. When a user clicks on a summary row, the CSS of the corresponding breakdown rows is changed using JavaScript.
I'd go with your first thought and perhaps either
load the data for the second table through an AJAX request returning only row data in JSON (or maybe even the HTML for the table)
use an UpdatePanel
if the user only needs to view the data, I would go for the former, but if they need to edit the data in some way, I would probably choose the latter (even though I'm aware that UpdatePanels are effectively a full postback in async clothing, I feel their use can make the UI more fluid).
You could also make an AJAX call when the user clicks on a row in the summary table to return the data for the 2nd table.
second way no way, loading all of data and then hiding showing is not a good idea, it will be slow and if you add more functionality it will only get in your way...
I recommend this two approaches:
1)first table with pagination
click on row triggers ajax call to page method
page method return second table
here, you can see how to that:

Ok so I have drop down list connected to a datasource, and I need to change 2 or 3 of the values before they are displayed and I'm just having trouble figuring out what to do. I'm assuming I setup some kind of loop to check the values, but thats all I can figure. Does anybody have any general suggestions or resources they know that I can look up? Thanks.
You need to do your processing before you bind the datasource. So for example, create a dataset of results or arraylist, process the results changing your values and then bind to your dataset/arraylist.
You'll need to be more specific about what you are binding to and how you want to process for me to be more specific..
