pyuic4 seems to generate a wrong layout based on a .ui file from Qt Designer. The UI file is here:

In this layout, I'm trying to align a pair of buttons with the bottom of the dialog window and some text with the top. Running pyuic4 test.ui --preview shows all objects aligned to the center horizontally, instead of to the top and bottom (and displaying this dialog from the actual python program shows the same results). By comparison, pyuic5 test.ui --preview seems to be more along the lines of what I wanted to get.
If it helps, my version of pyuic4 is 4.11.4 and I'm on Ubuntu 16.04.
Any ideas? Am I doing something wrong? Or is there perhaps a newer pyuic4 out there?
There was bug in pyuic that affected the handling of alignment in layouts. This was fixed in PyQt-5.5, which was released on the 17th July 2015. However, PyQt-4.11.4 (which is the current version) was released on the 11th June 2015 - so the fix has not been included, yet. The current development snapshot for PyQt-4.12 does includes the fix, though.
But I don't think this will really fix the issue you have. What you need to do instead is use expanding spacers. Here's how to do this using your example ui file:
Click on the horizontal button layout, and then click Break Layout (this will remove all the current layouts).
Ctrl+click the two buttons, and then click Layout Horizontally.
Click on the Dialog, and then click Layout Vertically.
Drag and drop a Vertical Spacer between the two Line widgets
Giving you this:
If you want to have some other widgets in the central area, you may need to add expanding vertical spacers above and/or below them to get the same results. Then again, if you put something like a text-box or list-widget in there, it should automatically expand to fill the available space - in which case, there wouldn't be any need for any spacers (or layout alignments).

A UI that I'm trying to create looks roughly like this:
Until now there's been no splitter, but now I want to put a movable splitter where the red line is and be able to drag it left or right.
So I used a QSplitter(using Qt Creator) and put it there ( where the red line is), but it doesn't work the way I want it; when I drag the splitter it doesn't 'slide' along with the mouse. Instead, it's like there are 3 options:
closing the menu side entirely ( and doing so badly; can't see the separator itself)
The 'normal' position (exactly as before dragging the separator)
Closing the content side entirely ( and doing that badly as well)
I'd love to provide more information but I don't really know what would be helpful. Please let me know what would be helpful.
Thanks.
UPDATE:
The code #bfris added here inspired me to create a mockup playground and try a bunch of things.
so I copied the content side and the menu side from my project to the playground, added a QSplitter and everything just worked great.
But then I tried to do the same in my project - and I saw the same behavior I described above .
So I played with my project a little more to investigate what could be the cause; I tried to leave the menu side (frame) empty - same behavior. Tried to leave the content side empty - and the QSplitter worked well(!).
So I brought the content back into my project and tried to change its' horizontal size policy to 'ignored' - and that worked too, but the proportions were waaay off; The menu side was initially bigger than the content side.
The interesting part is that at the playground I didn't have to change the size policy.
Any thoughts what might be the difference between the playground and the project? Or how to make the proportions right when horizontal size policy is 'ignored'?
I've not seen a QSeparator. QSplitters work very nicely and smoothly.
This is an example I worked up i Qt Designer. qsplitter_example.ui:

After much trial and error (thanks to #bfris who inspired me to create a mockup playground) I have found what the issue was.
Quite annoyingly, it appears that I have misplaced the content (of, well, the content frame) into the wrong frame!
Now That I moved it back to the correct frame, all I needed was to set the content frame's horizontal size policy to 'ignored'.

I'm a newbie how do I solve this?
My main question is I'm building a GUI application that has many widgets hence writing all those functions into a single file isn't a good practice hence while writing only I created 2 files I wrote half functionalities in one file and another half in another file (i thought we can connect files and everything will fine) so now I'm trying to make one of the main class and import other all into it but importing them alone isn't working so I'm confused how to do
my original GUI looks like this
tab 1
tab 2
each of these 2 tabs code is written in 2 separate files. and standalone code files workes file so now I want to add something in tab 1 file so tab 2 will also work fine.
A test GUI and code so someone can try to understand the problem more clearly
hence I made an example here
with 1 GUI and 2 dropdowns and 2 codes which work standalone for one dropdown
now my question is what are the changes to be done so i can run one file and import all other files info and run all functionality fully from only one file
My GUI (this is a sample made to test)

I added 2 combo_boxes and accessing them from 2 different files
I want this class to be the parent/main class
File one code that I want to make as a parent class (for number dropdown)
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QTextEdit, QFileDialog
from PyQt5 import uic
import sys
class Mainn(QMainWindow):
def __init__(self):
super(Mainn, self).__init__()
uic.loadUi("lol.ui", self)
self.show()
self.comboBox_select_number.currentIndexChanged.connect(self.updatenumber)
def updatenumber(self):
number=self.comboBox_select_number.currentText()
self.label_selected_number.setText(number)
app = QApplication(sys.argv)
window = Mainn()
app.exec_()
2nd file code for(gender dropdown)
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QTextEdit, QFileDialog
from PyQt5 import uic
import sys
class UI(QMainWindow):
def __init__(self):
super(UI, self).__init__()
uic.loadUi("lol.ui", self)
self.show()
self.comboBox_select_gender.currentIndexChanged.connect(self.updategender)
def updategender(self):
gender=self.comboBox_select_gender.currentText()
self.label_selected_gender.setText(gender)
app = QApplication(sys.argv)
window = UI()
app.exec_()
I do know when I run them separately they do only their specific work now I want to combine them so if run the main file both combo box should work suggest me minimal changes of code to work on it.
i do know we can combine like this into a single file and run
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QTextEdit, QFileDialog
from PyQt5 import uic
import sys
class Mainn(QMainWindow):
def __init__(self):
super(Mainn, self).__init__()
uic.loadUi("lol.ui", self)
self.show()
self.comboBox_select_number.currentIndexChanged.connect(self.updatenumber)
self.comboBox_select_gender.currentIndexChanged.connect(self.updategender)
def updatenumber(self):
number=self.comboBox_select_number.currentText()
self.label_selected_number.setText(number)
def updategender(self):
gender=self.comboBox_select_gender.currentText()
self.label_selected_gender.setText(gender)
app = QApplication(sys.argv)
window = Mainn()
app.exec_()
and it works
so I want to get the same functionality with the 2 files by somehow linking them
Hi Finally found a solution
I do know this isn't a good code and it may be completely wrong but I'm getting my required output.
File 1 code
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QTextEdit, QFileDialog
from PyQt5 import uic
import sys
class Mainn(QMainWindow):
def __init__(self):
super(Mainn, self).__init__()
uic.loadUi("lol.ui", self)
self.comboBox_select_number.currentIndexChanged.connect(self.updatenumber)
def updatenumber(self):
number=self.comboBox_select_number.currentText()
self.label_selected_number.setText(number)
file 2 code
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QTextEdit, QFileDialog
from PyQt5 import uic
import sys
from main import Mainn
class UI(QMainWindow):
def __init__(self, parent = None):
super(UI, self).__init__(parent)
self.ui=Mainn()
self.ui.__init__()
self.ui.show()
self.ui.comboBox_select_gender.currentIndexChanged.connect(self.updategender)
def updategender(self):
gender=self.ui.comboBox_select_gender.currentText()
self.ui.label_selected_gender.setText(gender)
app = QApplication(sys.argv)
window = UI()
app.exec_()
now if i run file 2 it works as per my requirement
If still their are any improvements please let me know thank you

I am a bit new for Ignite. I walk through documentation but unable to find. Is any way to setExpiryPolicy into XMl?
Any help would be appreciated!
That requires a bit of Spring XML magic because there is no easy-to-use factory class for the CreatedExpiryPolicy (i.e. no CreatedExpiryPolicyFactory that you can just instantiate like a normal bean), but there is the CreatedExpiryPolicy::factoryOf that can be passed as factory-method:
<property name="expiryPolicyFactory">
<bean class="javax.cache.expiry.CreatedExpiryPolicy" factory-method="factoryOf">
<constructor-arg>
<bean class="javax.cache.expiry.Duration">
<constructor-arg value="SECONDS"/>
<constructor-arg value="10"/>
</bean>
</constructor-arg>
</bean>
</property>
Apache Ignite doesn`t support expiry policies and TTL for SQL tables.
An alternative would be to create cache with dynamically generated names based on desired time window.
For example you could append hour of the day if you need it hourly:
MY_CACHE_00
MY_CACHE_01
MY_CACHE_02
etc...
MY_CACHE_23
Then make your software write/read to the latest hour CACHE, and clear the oldest.
I'm trying to integrate Apache Ignite with Apache Cassandra(3.11.2) as I want to use Ignite to cache the data present in my already existing Cassandra database.
After going through the online resources, I've done the following till now:
Downloaded Apache Ignite.
Copied all the folders present in "libs/optional/" to "libs/"(I don't know which ones will be required for Cassandra).
Created 3 xmls in the config folder i.e. "cassandra-config.xml", "connection-settings.xml" and "persistance-settings.xml". Currently I'm using the same node(172.16.129.68) for both Cassandra and Ignite.

I run the following command to start Ignite from bin folder.
ignite.sh ../config/cassandra-config.xml
Now, I want to take a look at the cassandra table via sqlline. I've tried the following:
./sqlline.sh -u jdbc:cassandra://172.16.129.68:9042/test //(test is the name of the keyspace)
I get the following output:
No known driver to handle "jdbc:cassandra://172.16.129.68:9042/test". Searching for known drivers...
java.lang.NullPointerException
sqlline version 1.3.0
0: jdbc:cassandra://172.16.129.68:9042/test>
I've also tried:
./sqlline.sh -u jdbc:ignite:thin://172.16.129.68
but when I use "!tables", I'm not able to see any table.
What exactly has been missing? How to access/modify the tables present in Cassandra using sqlline?
Operating System: RHEL 6.5
Apache Ignite is a key-value database and there are no tables created by default that you are able to view with JDBC connector. CacheStore is a way to integrate Ignite with external DB or any other storage, and it loads data as a key-value pair.
In your config you said Ignite that you want to store and load entries in/from Cassandra, but still Ignite doesn't know entries structure (BTW Ignite really doesn't care what objects were putted into it).
To be able to list tables and do queries on it, you need to create tables. For that you need to have ignite-indexing in /lib directory and set QueryEntity or indexed types if you have annotated POJOs. Here is example of such configuration:
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="mycache"/>
<!-- Configure query entities -->
<property name="queryEntities">
<list>
<bean class="org.apache.ignite.cache.QueryEntity">

If you configure that, you'll get an ability to enlist and query that tables over SQLine. (Please note, that you cannot query data that are not loaded into Ignite. To load them, you may use IgniteCache.get() with enabled readThrough option or IgniteCache.loadCache() to load everything from Cassandra table).
To query Cassandra with JDBC, you need a JDBC driver for it, try, for example DBSchema.
I have a custom control as shown below.
During uninstall the condition that checks for IIS_MAJOR_VERSION="#7" AND IIS_MINOR_VERSION="#5" seems to fail although during install this condition is true.
I did check in the uninstall file that the property for IIS_MAJOR_VERSION="#7" AND IIS_MINOR_VERSION="#5". Does anyone know what did I do wrong?
<Property Id="IIS_MAJOR_VERSION">
<RegistrySearch Id="CheckIISVersion"
Root="HKLM"
Key="SOFTWARE\Microsoft\InetStp"
Name="MajorVersion"
Type="raw" />
</Property>
<Property Id="IIS_MINOR_VERSION">
<RegistrySearch Id="CheckIISMinorVersion"
Root="HKLM"
Key="SOFTWARE\Microsoft\InetStp"
Name="MinorVersion"
Type="raw" />
<Custom Action="DropDBUSerIIS75" Before="InstallFinalize">Installed AND NOT UPGRADINGPRODUCTCODE AND IIS_MAJOR_VERSION="#7" AND IIS_MINOR_VERSION="#5"</Custom>
Even I am not sure about the code why is it going wrong, but for precaution use this code to get the value of IIS version because even if IIS is un-installed the above registry key values will persist.
