python - Get the index of a QTableWidget row knowing its elements -

[i'm using pyqt4, think qt4 issue not python specific.] i have qtablewidget . in each row, first column holds button. when clicked, row removed. to remove row, use removerow(int row) method, takes argument index of row. when connecting signal, can't know index of row because might change in meantime (for instance if first row removed, row indexes changed). the accepted answer here suggests pass callback instance of qtablewidgetitem in line, row number item @ deletion time. this nice, except none of elements of row qtablewidgetitem . elements button , few comboboxes. i can't figure out way around this. can somehow fit 1 of elements qtablewidgetitem? should add qtablewidgetitem in sort of hidden column? our current implementation uses indexat(qtgui.qapp.focuswidget()) (see other answer question mentioned above), looks sorry workaround me. if replace button checkable qtablewidgetitem this rm_item = qtgui.qtablewidgetitem() rm_item.setflags(qtcore.qt.it

c# - Shunting-Yard Validate Expression -

we use shunting-yard algorithm evaluate expressions. can validate expression applying algorithm. fails if there missing operands, miss-matched parenthesis, , other things. shunting-yard algorithm has larger supported syntax human readable infix. example, 1 + 2 + 1 2 1 2 + are acceptable ways provide '1+2' input shunting-yard algorithm. '+ 1 2' , '1 2 +' not valid infix, standard shunting-yard algorithm can handle them. algorithm not care order, applies operators order of precedence grabbing 'nearest' operands. we restrict our input valid human readable infix. looking way either modify shunting-yard algorithm fail non-valid infix or provide infix validation prior using shunting-yard. is aware of published techniques this? must support both basic operator, custom operators, brackets, , functions (with multiple arguments). haven't seen works more basic operators online. thanks a nice discussion on shunting yard algorithms

i have bunch of toolstrip buttons transparent backgrounds in wpf. when user mouses on outside of button, nothing happens, because part of button transparent. once user mouses on 1 of non-transparent areas of button, "hover" behavior changes border , background color. background no longer transparent, hover behavior continues larger area before. transparent areas of button behave if button non-transparent there. that is, have behavior button unselected despite mouse being inside button area: and i'm trying button selected if user has not moused on foreground "white" part of button: i tried setting ishittestvisible on button itself, didn't seem make difference. is there way ask wpf consider transparent areas of button significant? xaml looks this: <button style="{staticresource maintoolstripbuttonstyle}" margin="5,0,0,0" tooltip="{staticresource openbuttontext}" automationproperties.name="{staticresour

dll - How can I use matlab source code in labview without matlab? -

i found mathscript can this,but seem slow. want use matlab create dll file used labview,but information can find how dll used in c++,but c++ must use .lib file ,i concerned labview not use lib. file. so can use .dll in labvew,and how?is there anyother way use matlab source code in labview without matlab? you need purchase matlab compiler quite expensive unless student. you can call matlab application (if it's installed) using matlab script node (which different mathscript) - see here another alternative python's numpy picked coming matlab background. if want go down route can give further advice on how integrate labview.

ember.js - container.lookup('store:main') returning undefined -

i'm using emberjs , have initializer loading current user in store. have no idea why not working. current initializer is: export function initialize(container, application) { var store = container.lookup('store:main'); console.log(store); } export default { name: 'current-user', after: 'preload', initialize: initialize }; when log container , convert global variable in console, , run temp1.lookup('store:main') object. i'm pretty confused right why initializer isn't able load store. it's because initializer running before 1 sets store. ember data initializer can found here . described in initializer api , need this: export default { name: 'current-user', after: ['preload', 'ember-data'], initialize: initialize };
