  @rrraptor , for the mirrored filled slider i need that the values are also reversed (that is, it goes from 100 to 0). i can set the range to 100,0 but strangely then i cannot pull it to to 0, the filledslider stops at 1.
  

  Same for regular "sliderInt", so that is a bug in original ImGui code. I'll try to fix it.
  
  Btw its ok for float slider

  imgui:filledSliderFloat("test1", true, v1, 100, 0, "%.0f")

  i see in docs that textinput is still pending.
  i'm not even sure i need it urgently.
  i want to be able to click on a text and edit it (but otherwise it should not 'look' as editable like a regular textinput).

  that is also quite useful link:

  i wish there was a lua equivalent, but even this way it's a big help.

  @rraptor, what is the current status of your imgui plugin ? I made scripts to compile it for all platforms and I am almost ready to build Gideros 2020.9

  @hgy29 well, I was very busy last week, so not that much has changed. Ive updated ImGui to 1.78 and made some changes to readme on my github page and that is it. Also I created a bug report (?) on github.
  Current TODO list:

  • Fonts API (io.Fonts related methods)
    
  • Text input
    
  • Finish custom drawing
    
  • Touch support
    
  • Fix some functions with overloads (e.g. different amount of arguments)
    
  • Remove some internal use only enums
    
  • Find and fix bugs
    

  If you want, you can add it. Ive uploaded my latest version to github.

  Ty, Ill fix it later
  
  Also, I added custom flag for text inputs that alows you to ignore background drawing
  
  Code:

  myInputText = imgui:inputText("No background\nsingle line\ntext edit", myInputText , 128, ImGui.InputTextFlags_NoBackground) myInputText = imgui:inputText("Normal single line\ntext edit", myInputText , 128)   myInputText2 = imgui:inputTextMultiline("No background\nmultiline text edit", myInputText2, 512, 0,0,ImGui.InputTextFlags_NoBackground) myInputText2 = imgui:inputTextMultiline("Normal\nmultiline text edit", myInputText2, 512)

  @rraptor, your code doesn't compile with visual studio! I am changing all VLA definitions to standard C++ way, please don't use them anymore.

  thanks @rrraptor , no background is pretty cool, now i don't need to add a popup to do this. is there a flag to make the title appear before (i.e., left to) the inputtext area?

  User bitwise OR like this:

  ImGui.InputTextFlags_Password | ImGui.InputTextFlags_CharsUppercase

  But it can go wrong on mobiles in the future. See: http://forum.giderosmobile.com/discussion/8108/bitwise-operations-on-android

  Sorry VLA are "variable length arrays".
  In standard C++, you can't write:

  char buffer[buffer_length];

  unless buffer_length is a constant. Instead you have to allocate it dynamically:

  char *buffer=new char[buffer_length]; ... delete[] buffer;

  It works on QT because clang and gcc compilers do support VLA, unfortunately MSVC doesn't...

  Ah, sorry, did know about that. I'll fix it someday

  Hmm, seems like there is no way
  Solution is simply use widget combination like this:

  imgui:text("...") imgui:sameLine() imgui:inputText("", text, 100)

  I'll do Ty.
  
  @keszegh
  You can detect if enter pressed like that:

  myInputText,myInputTextFlag = imgui:inputText("No background\nsingle line\ntext edit", myInputText , 128, ImGui.InputTextFlags_NoBackground | ImGui.InputTextFlags_EnterReturnsTrue) --myInputTextFlag is true after "enter" is pressed

  But it does not work if text box is unfocused by clicking somewhere else.

  @hgy29 I can switch to VS too I just need to know how to setup everything )))
  Also I tried to switch to FreeType instead of TrueType font lib (to fix "sharp edges" problem), but no success xD It requires dynamic (?) library which I dont know how to "connect"/"include" to the project.

  @rrraptor , do you know how can i hide X close button on a window? i've found this:
  https://github.com/ocornut/imgui/issues/1305
  but can't translate it to what it would mean in lua.

  but can't translate it to what it would mean in lua.

  Fixed.
  Now you can simply do that:

  if imgui:beginWindow("YOU CANT CLOSE ME", flags) then imgui:text("Hi") end imgui:endWindow()

  @rrraptor , yes the ImGui.WindowFlags_XXXX actually worked for me using them as you suggested, the issue is that there is no flag to prevent the window from closing (or i haven't found).
