I had another look at this.  It seems to happen only with certain window managers.

I'll take a look to see if I can fix it.

In the meantime I suggest using a tiling window manager such as ratpoison for which the problem doesn't manifest itself.

This is odd.  For me this operation is almost instantaneous. (< 0.5 sec)

I wonder why for other people it takes so long ...

I can confirm this on MacOS. It takes a couple of minutes to delete 10 variables. To reproduce:

  • Open grid.sps and create the grid datasheet
  • Go to data view
  • Select variables 110 - 120
  • Delete these by right-clicking "variable löschen"

=> Takes ages.

I attached a screenshot from the XCode Instrumentation, showing that psppire hangs in the libspread-sheet-widget in "ensure_visible_widgets".

Dear Ben,

About 200 Variables per about 120 cases. I delete about 10 variables per time.

I have installed both PSPP v1.2.0 and v1.0.1. I installed them from source.

The difference is between whole minutes and some seconds. Huge difference!

I know some coding e.g. python or debugging tips. If you tell me what to do, I can post more helpful information.

Sincerely,
Elias Tsolis

p.s. I use PSPP as statistician, so it is a handy tool for me.

p.s. Happy New Year

p.s. I would interest to be involved in developing PSPP. However, my knowledge of hardcore program coding is -at least- childish. I used python as statistical / graph package.

Wow, that's really slow!

Approximately how many variables do you have?  (Ten, a hundred, a thousand?)

Approximately how many cases do you have?  (Ten, a hundred, a thousand, more?)

How many variables are you deleting at a time?

In Lubuntu, in PSPP v.1.2.0, deleting variables, takes so much time.

Process:

Pressing down shift + left mouse click, in Variable View pspp window, then right mouse click on the selected "variable numbers", and pressing "clear" or through menu.

It is taking so much time... whole minutes for clear 10 variables!

This behaviour was not found in previous editions. I could upload video, if this can help.

Sincerely,
Elias Tsolis
