web applications - SmartGWT TreeGrid Selection -

-

I have a SmartGWT web app that uses a datasource with a tree grid. I would like this grid to select the tree saved values ​​in a cookie. I have got the value to save in the cookie correctly, although I tried many different ways of picking tree grids to choose these values. And I can not get it to work. I'm trying to do this on my entry point in the onmoduleLoad method

I tried: 

  Cookies set cookies to set cookies ("Selected UIIT", Treegrid.Get selected path ())

And then when the page is reloaded: 

  TreeGrid.setSelectedPaths (Cookies.getCookie ("selectedUnit")
When I could not find it to work, I tried to store the ID only, selected items: 

  cookie cookies ("cookies") GoedAttribute ("id"))

and then attempt to overload it to find that record and select it:

< Pre> TreeGrid.selectRecord (TreeGrid.getTree (). ("Id", Cookies.getCookie ("selectedUnit"))

This does not work either, so Finally, I tried to store a treegrid .customized () and the cookie onload after recovering that value, it triggering. The path selected from the set (), similar to my first attempt. / P>

I could not work on any of these jobs. Can I not tell Trigrid to choose an item in 'Onamod' Ule Load 'method? Is this action valid only after tree grid? If that is the case and how can I do this?

Thank you in advance for any help.

I thought it:

I finished using set (/ received) Happened SelectedState The issue I established was calling by setting up the Selectionstore in the Constructor, that the data was actually trying to set the selected state before it was there. I fixed it by setting an ondataarid handler for the tree and then expanding the tree (to get all the data) and then setting the selected position.

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
