Softwarová sklizeň (15. 8. 2018)

Root.cz - 20 hodin 22 min zpět
[1 minuta čtení] Sonda do světa otevřeného softwaru. Dnes se podíváme na přizpůsobitelnou virtuální klávesnici, vyzkoušíme nástroj pro testování webových stránek, vytvoříme spustitelný soubor z python skriptů a nakonec si ověříme integritu souboru. Celým názvem Unicode Virtual Keyboard je virtuální klávesnice postavená na JavaFX, se kterou můžete procházet znaky dle kategorií, vyhledávat znaky na základě jejich názvu, přidávat a mazat znaky, přistupovat k často používaným a oblíbeným znakům rychleji, kopírovat je do schránky či vkládat do jiných aplikací. V okně je zobrazen i přehled nedávno použitých kláves (znaků).
