Find dialog created from Qt.Class in header file define member function and variable complex since start coding.Once problem coding properties and event of dialogs.I cannot remember all variable of class( although Tools provide key completion for show variable in classes).Dialog write in paper can scope variable for coding.Good choice for coding and can seen image between coding.

After built Retroshare with script.Script advise by Max( Dooble Developer ).It's cannot process all job in script because set "exit" before download Retroshare.I move exit command to end line of script.

From chatsiri.com

Behind build project with "qmake" command for create libretroshare.pro are problems about library path and include path.It's can see link here for install Retroshare in Linux OS.One problem found in "MakeFile" at directory retroshare-gui is cannot found "lgpgme".

From chatsiri.com

Line at define "LIBS",You able config MakeFile path specific libgpgme by start with -L flag(I found library name libgpgme at path "gpgme-1.1.8/src/.libs").Example :

-L/gpgme-1.1.8/src/.libs
Thus,
LIBS = $(SUBLIBS) [...] gpgme-1.1.8/src/.libs/ -lgpgme [...]

After save MakeFile in retroshare-gui and type make command again.
Other problem with include path.It can specific path with "INCPATH" for include header file.Assume after show error "I cannont find "gpgme.h" in directory."(I found problem among build retroshare-gui.It's show Networkdialog.o cannot found "gpgme.h" in directory).MakeFile able to specific path by at "INCPATH" line.See example below.

INCPATH = [...] -I/gpgme-1.1.8/src/ [...]

After save MakeFile and type Make command again.Success!.

ก่ะว่าจะเขียนเรื่องที่เกี่ยวกับ Qt สักหน่อยเพราะตอนนี้
เพราะว่าอยากเขียนเรื่อง ของ Tools แบบ RAD(Repid Application
Development)[link]ภายใน Linux และตัวของ Qt เองยังมี Qt
Designer ที่สามารถสร้าง dialog แบบลากวาง( Drop and Drag)
[link] เป็นว่าผมเตรียมเรื่องราวที่จะเขียนไปพร้อมๆ กับ java เดือนหน้า
ประมาณกลางเดือนจะเป็นคิวของการไปอบรมเกี่ยวกับ VHDL เสียที(อยาก
จะไปอบรมเผื่อได้อะไรเพิ่มเติมจาก nectec)

Begin you learn Qt component should know about
Signal and Slots.
void Counter::setValue(int value)
{
if (value != m_value) {
m_value = value;
emit valueChanged(value);
}
}

Concept of signal and slot .First signal community
to slot such as signal--->slot.Tookit use strategy
callback from function call.Them are callback two
fundamental:One not type-safe ,can never be
certain that process function.Two callback
strongly coupled processing function.Above you
see Counter::setValue from example[link]
it's good example use signal and slot.
