java - TreeViewer#update(Object element, String[] properties); what do properties refer to? -

-

मैं पद्धति TreeViewer # update (Object) में पैरामीटर properties के बारे में सोच रहा हूं तत्व, स्ट्रिंग [] गुण) । वे क्या हैं? वह किसका उल्लेख करते है? मुझे यकीन नहीं है कि क्या स्ट्रिंग [] में जाता है - क्या उपयोग करने के लिए पूर्वनिर्धारित स्थिरांक हैं? या ये मेरे कॉलम हेडर के नाम हैं? कुछ और?

मुझे update () के उपयोग का कोई भी उदाहरण नहीं मिल सका है, जिस पर null पास नहीं है गुणों के लिए मान Javadoc मेरे लिए वास्तव में उपयोगी नहीं है।

धन्यवाद!

यह बताता है अध्याय 'बदलने के लिए जवाब' में उन गुणों के लिए किस प्रकार उपयोग किया जाता है: यदि आप वृक्षारोपण के लेबल या सिर्फ लेबल के पाठ या लेबल की छवि का पूरा अद्यतन करना चाहते हैं तो आप ठीक कर सकते हैं। गुणों को कैसा दिखना चाहिए इसके बारे में विस्तार में नहीं जाना है। उसे, मुझे लगता है, आपको सीधे स्रोत कोड का अध्ययन करना होगा, अगर जवाडॉक्स पर्याप्त नहीं हैं।

c# - ListView onScroll event -

-
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...
