પટેલ સમાજનો ઈતિહાસ જાણો : કોણ અને ક્યાંથી આવ્યા હતા પાટીદારો

PATIDAR The  Patidar  are a  caste  found in the state of  Gujarat , India. They were formally recognized as a separate identity in the 1931 census of India, having previously been classified as  Kanbi . They are among the most studied of Indian castes and the process leading to their recognition is a paradigmatic example of the  invention of tradition  by social groups in India. પટેલ અથવા પાટીદાર અથવા કણબી એ ભારત દેશનાં પશ્ચિમ ભાગમાં આવેલા ગુજરાત રાજ્યની એક મુખ્ય જ્ઞાતિ છે. પટેલોમાં લેઉવા પટેલ અને કડવા પટેલ એમ બે પેટા જ્ઞાતિ છે. ઇતિહાસ તેઓ કુર્મઋષિનાં વંશજો હોવાનુ મનાય છે તેથી તેઓ શરૂઆતમાં કુર્મી તરીકે જ ઓળખાતા હતાં. ઇતિહાસકારોનાં મત અનુસાર પટેલો મધ્ય એશિયા માં આસુ નદી પાસે પામીર નામનાં ઉચ્ચ પ્રદેશમાં વસતા હતાં. ત્યાંથી એક સમુહે અફઘાનિસ્તાન માં થઈને હિન્દુકુશ પર્વતમાળા ઓળંગી ખૈબરઘાટનાં માર્ગે પંજાબ માં દાખલ થઈને વસવાટ કર્યો હતો તેમ કહેવાય છે. ભારત દેશમાં પંજાબના સપ્તસિંઘુ પ્રદેશ ‘લેયા’ પ્રદેશમાંથી આવેલા કૂર્મિ ક્ષત્રિયો લેઉઆ કહેવાય...

Java Event Delegation Model, Listener and Adapter Classes

Image
Java Event Delegation Model The Delegation Event model is one of the many techniques used to handle events in GUI (Graphical User Interface) programming languages. GUI represents a system where an user visually/graphically interacts with the system. Other interactive systems are text based or called CUI (Character User Interface). CUI interacts with the system by typing out commands in the console. GUI programming is inherently event driven; that means, whenever an user initiates an activity such as a mouse move that changes the co-ordinates of the mouse pointer in the screen, or clicks a button, scrolls a page, and so forth, each is deemed as an event that the GUI event handler maps the activity to a piece of code that explains what response the application should provide to the user. Any program that uses GUI (graphical user interface) such as Java application written for windows, is event driven. Event describes the change in state of any object.  For Example:  Pre...
