I'm trying to write an application using gtkmm, and I want it to hide the mouse cursor when it has focus. So the first step I tried is I hide mouse cursor when the cursor is on top of my window, which is successful. But to prevent the mouse from showing when it is moved outside of my window, I then restrict the mouse movement by constantly warp the mouse cursor back to the center of my drawing area.
To do this I need to know the window position and the size of the window, which are easy to get using Gdk::Window::get_position and Gdk::Window::get_size. However, if the window is moved, get_position will not return the updated position and thus my cursor will to frozen at a wrong position!
So what are the alternatives to achieve the effect that I want here?
Just grab the pointer.
//pass all events to window apart LEAVE_NOTIFY_MASK
MainWindow->set_events(GDK_EXPOSURE_MASK | GDK_POINTER_MOTION_MASK | GDK_POINTER_MOTION_HINT_MASK | GDK_BUTTON_MOTION_MASK | GDK_BUTTON1_MOTION_MASK | GDK_BUTTON2_MOTION_MASK | GDK_BUTTON3_MOTION_MASK | GDK_BUTTON_PRESS_MASK | GDK_BUTTON_RELEASE_MASK | GDK_KEY_PRESS_MASK | GDK_KEY_RELEASE_MASK | GDK_ENTER_NOTIFY_MASK | GDK_FOCUS_CHANGE_MASK | GDK_STRUCTURE_MASK | GDK_PROPERTY_CHANGE_MASK | GDK_VISIBILITY_NOTIFY_MASK | GDK_PROXIMITY_IN_MASK | GDK_PROXIMITY_OUT_MASK | GDK_SUBSTRUCTURE_MASK | GDK_SCROLL_MASK | GDK_TOUCH_MASK | GDK_SMOOTH_SCROLL_MASK | GDK_TOUCHPAD_GESTURE_MASK);
MainWindow->set_modal(true);
auto display = MainWindow->get_display();
auto window = MainWindow->get_window();
auto grabSuccess = display->get_default_seat()->grab(window, Gdk::SEAT_CAPABILITY_ALL, true);
if(grabSuccess != Gdk::GRAB_SUCCESS)
{
std::clog<<"grab failed: "<<grabSuccess<<std::endl;
}

Consider the following data:
Item | Overall | Individual | newColumn
A | Fail | Pass | blank
A | Fail | Fail | blank
B | Fail | Pass | issue
B | Fail | Pass | issue
C | Pass | Pass | blank
I have the logic built out for the first 3 columns already. There are two levels of fails in this data:
overall, and
individual.
If any of the individual fail, the overall fails. Sometimes the overall can fail even though all the individuals are fine. This logic is already built out.
I am trying to find a formula for the newColumn. If all the individuals are a pass for a given item (example item B), but the overall is still a fail, the cell should return the text "issue". It is ok if it returns issue twice, not sure if you can non-dupe that part. I've tried various forms of countifs/and/ors and creating columns that count distinct values but I always find a scenario where it will break the logic.
Try this:
=IF(COUNTIFS($A$2:$A$6,A2,$C$2:$C$6,"Fail"),"blank",IF(B2="Fail","Issue","blank"))
As required
If you add a new column with the formula:
=IF(B2="Fail",IF(COUNTIFS(A:A,A2,C:C,"fail")=0,"issue",""),"")
Then this should work on the assumptions:
For each item if one of the overalls are false they are all false
The only two possible values are "Pass" and "Fail" for columns B & C
If you require the word blank instead of a blank cell then use:
=IF(B2="Fail",IF(COUNTIFS(A:A,A2,C:C,"fail")=0,"issue","blank"),"blank")
I need to create a SSIS project that loads daily batches of 150 files into a SQL Server database. Each batch always contains the same 150 files and each file in the batch has a unique name. Also each file can either be a full or incremental type. Incremental files have one more column than the full files. Each batch contains a control file that states if a file is full or incremental. See example of a file below:
Full File
| SID | Name | DateOfBirth |
|:---: | :----: | :-----------: |
| 1 | Samuel | 20/05/1964 |
| 2 | Dave | 06/03/1986 |
| 3 | John | 15/09/2001 |
Incremental File
| SID | Name | DateOfBirth | DeleteRow |
|:---: | :----: | :-----------: | :----------: |
| 2 | | | 1 |
| 4 | Abil | 19/11/1993 | 0 |
| 5 | Zainab | 26/02/2006 | 0 |
I want to avoid creating 2 packages (full and incremental) for each file.
Is there a way to dynamically generate the column list in each source/destination component based on the file type in the control file? For example, when the file type is incremental, the column list should include the extra column (DeleteRow).
Let's assume my ControlFile.xlsx is :
Col1 Col2
File1.xlsx Full
file2.xlsx Incremental
Flow:
1.Create a DFT where ControlFile.xlsx is captured in an object variable. Source : Control connection, Destination : RecordSet Destination
Pass this object variable in ForEach loop. ResultSet variable should be capturing Col2 of ControlFile.xlsx.
Create a Sequence container just for a start point. Add 2 DFD for full load and incremental load. Use the constraints (as shown in below
image) to decide which DFD will run.
Inside DFD, use excel source to OLEDB destination.
Use FilePath variable for connection property in Full load and incremental excel connections to make it dynamic.
Step1: overall image
Step2:
In DFT - read control file, you read the FlowControl.xlsx to save it RecordSet destination, into RecordOutput variable
Step3:
Your precedence constraints should look like below image("Full" for full load, "Incremental" for incremental load ) :
Use the source and destination connections as shown in first image. It's a bit hard to explain all the steps, but flow is simple.
one thing to notice is, you have additional column in Incremental, hence you'll need to use 'Derived Column' in your full load for correct mapping.
Also, make sure DelayValidation property is set to true.
For each loop container uses For each ADO Enumerator. Following images describe the properties :
AND
I can think of two solutions.
1) Have a script task at the beginning of the package that looks to see if this is an incremental load or a full load. If it is a full load, have it loop through all the files and add a "DeleteRow" column with all zeros to every file. Then you can use the same column list.
2) Use BiML to dynamically generate your package at run time based on the available metadata.
Hi I'm quite new in Pentaho Spoon and I have a problem:
I have a table like this:
model | type | color| q
--1---| --1-- | blue | 1
--1---| --2-- | blue | 2
--1---| --1-- | red | 1
--1---| --2-- | red | 3
--2---| --1-- | blue | 4
--2---| --2-- | blue | 5
And I would like to create a single table (to export in csv or excel) for each model grouped by type with the value of the group as header and as value the q value:
table-1.csv
type | blue | red
--1--| -1-- | -1-
--2--| -2-- | -3-
table-2.csv
type | blue
--1--| -4-
--2--| -5-
I tried with row denormalizer but nothing.
Any suggestion?
Typically it's helpful to see what you have done in order to offer help, but I know how counterintuitive the "help" on this step is.
Make sure you sort the rows on Model and Type before sending them to the denormalizer step. Then give this a try:
As for splitting the output into files, there are a few ways to handle that. Take a look at the Switch/Case step using the Model field.
Also, if you haven't found them already, take a look at the sample files that come with the PDI download. They should be in ...pdi-ce-6.1.0.1-196\data-integration\samples. They can be more helpful than the online documentation sometimes.
Row denormalizer can't be used here if number of colors is unknown, also, you can't define text output fields dynamically.
There are few ways that I can see without using java and js steps. One of them is based on the following idea: we can prepare rows with two columns:
Row Model
type|blue|red 1
1|1|1 1
2|2|3 1
type|blue 2
1|4 2
2|5 2
Then we can prepare filename for each row using Model field and then easily output all rows using text output where file name is taken from filename field. In this case all records will be exported into two files without additional efforts.
Here you can find sample transformation: copy-paste me into new transformation
Please note that it's a sample solution that works only with csv. Also it works only if you have the same number of colors for each type inside model. It's just a hint how to use spoon, it's not a complete solution.
I have the variable labels and value labels in a table in my database, like this
id_variable_label | variable_label | id_value_label | value_label | id_father_label
---------------------------------------------------------------------------------------------------------
1 | father_label | null | null | null
null | father_label | 1 | child01 | 1
null | father_label | 2 | child02 | 1
Is there a way to generate automatically all the variables and value labels when I import the data from my database through a ODBC connection?
There isn't a direct way to do this, but if you read that table as an SPSS dataset, it would be pretty simple to generate the labels with a little Python code.
Note also that if your labeling is static, you can use APPLY DICTIONARY to copy labels from one dataset to another, so saving one fully labeled file would allow you to propagate that to others that are similarly structured.
You can use SPSS syntax to create variable and value labels.
See the SPSS commands VARIABLE LABELS and VALUE LABELS.
Here's a tutorial here that explains how you can use them.
You could generate the syntax from your database.
How do I build the following view?
I want to build a form using a standard UITableViewController, but I need to have an image that spans the first two rows. Rows have text in them (not pictured).
One way I've considered is to have the Image and first two rows actually be one row with another UITableView embedded inside it, with scrolling disabled.
But I'd really like to do something with indenting.
UITableView
+-----+---------------+
| | | <---+ Row 0
UIImageView +---> | +---------------+
| | | <---+ Row 1
+-----+---------------+
| | <---+ Row 2
+---------------------+
| |
+---------------------+
| |
+---------------------+
| |
+----------------
|
+-----------
|
+------
| Etc..
+--

How can I accomplish this, using the fewest widgets / least amount of code (for iOS 4+)?
You've probably realized this isn't standard, so I think your three options are:
Two images that fit to look like one.
rows 1 & 2 are actually 1 row that looks like it's two rows.
row 1 has an image as big as the first two rows, and subview clipping is off so it overlays row two.
I'd be inclined to use option #1, but if the images will change or be dynamic, I might go for option #2
I ended up putting a UIImageView and a nested UITableView inside the row 0 UITableViewCell. The nested UITableView has scrolling disabled and provides one group with two rows. Then I just had to fudge the frame a bit.
I think your best bet would be to subclass UITableViewCell for your first 2 cells. You should be able to lay it out to look like 1 big cell or your rowspanned cells, then just use the default for all the remaining cells.
