@keszegh Thanks, that worked...

keszegh · July 2021

@SinisterSoft , any idea about the imageButtonWithText width adjustment? you seem to use such buttons yourself.

SinisterSoft · July 2021

						if not stackedButtons and b[loop,2]=="" then
							if ui:imageButton(b[loop,5],size-6,size-6) then
								callButton=loop
							end
						elseif ui:scaledImageButtonWithText(b[loop,5],b[loop,2],size,size,w,size) then
							callButton=loop
						end

					local size=35
					local w=ui:getWindowContentRegionWidth()
					local iw=w
					if not s.stackedButtons then
						size=16
						local c=#b
						for loop=1,#b do
							if b[loop,2]=="" then
								w-=(size+spX+2)
								c-=1
							end
						end
						if c>0 then w=((w+spX)/c)-spX end
					end

stackedbuttons is false
b is a table with icon pointers, text, hint. if the text is "" then it makes a button with no text.

size is basically the size I want the icon to be with w being the actual button width.

The routine will auto-size the buttons to the width available.

@SinisterSoft , strange that you do this and it works properly
ui:scaledImageButtonWithText(b[loop,5],b[loop,2],size,size,w,size)
as it's supposed to be:
pressFlag = ImGui:scaledImageButtonWithText(texture, text, w, h, [padding = -1, bgColor = 0xffffff, 0,tintColor = 0xffffff, 1, nil, nil, anchorX = 0.5, anchorY = 0.5])
so you set w for padding and size for bgColor?

keszegh · July 2021

@rrraptor , the arguments for scaledImageButtonWithText are wrong in the docu, i don't know what's the correct way though:
pressFlag = ImGui:scaledImageButtonWithText(texture, text, w, h, [padding = -1, bgColor = 0xffffff, 0,tintColor = 0xffffff, 1, nil, nil, anchorX = 0.5, anchorY = 0.5])

keszegh · July 2021

@SinisterSoft , your code helped me to see that the args for scaledImageButtonWithText are wrong in the documentation. yet this way i'm unable to set padding and tintColor, which i also need.

keszegh · July 2021

alas for imageButtonWithText there also should be some way to set width.

SinisterSoft · July 2021

There should be - but it looks like the docs are not in sync with the code. I think there are extra parameters that do stuff - try setting what you need after the iconw,iconh,boxw,boxh fields (or look at the source on github?)

i looked at the source briefly but i did not manage to do what i wish after a short look. perhaps @rrraptor will sort it out for us quickly.

You can always peek into source code:
https://github.com/MultiPain/Gideros_ImGui/blob/4f7605ba706ea951a73a0874a4488f19233c1558/main.cpp#L2804

scaledImageButtonWithText(texture, label, image_w, image_h, button_w, button_h, image_side, flags, tint_color, tint_alpha, bg_color, bg_alpha)

luaL_checknumber(L, X) -- https://pgl.yoyo.org/luai/i/luaL_checknumber
luaL_optinteger(L, X, 0) -- https://pgl.yoyo.org/luai/i/luaL_optinteger
X - 1 = LUA argument number

keszegh · July 2021

thanks @rrraptor .

keszegh · July 2021

@rrraptor , is there a way to set width of imageButtonWithText too?

SinisterSoft · July 2021

You may like this for automatically setting the default theme on html5 exports:

The screenshots are my app that uses the imgui plugin.

imgui:pushStyleVar(ImGui.StyleVar_ChildBorderSize,1) does not seem to have any effect. is it a bug or just something with my code?

keszegh · July 2021

imgui:showLuaStyleEditor() seems to need something as input?

rrraptor · July 2021

@keszegh there is no way

Ill try to fix this today.

Title as #1 param

keszegh · July 2021

i want to emulate an item being hovered/clicked. what is the most intelligent way to do this?
what i want to achieve is that a button and a checkbox are glued together and i want that if i hover on any of them then the other also gets into hovered (visual) state. also if i click on any of them then the other also gets into clicked (visual) state.

the logic of setting the checkbox also if the button gets clicked i could do easily but the visual side seems to be more complicated. i guess with setting manually
imgui:setStyleColor(ImGui.Col_Button, ...) for the other item would work but it needs to save state across multiple enterframe events etc. so i just hope there is a nicer solution.

keszegh · July 2021

another bug with dragint:
if i double-click or ctrl-click to input exact value then while in this input mode i guess the state should be active (when queried with imgui:isItemActive()). now it is not and this messes up my tooltip behaviour (the help text is kept shown even if i move the mouse).

e.g. sliderInt works properly in this respect, when ctrl-clicked to input value directly then it gets into active state.

keszegh · July 2021

yet another question:
if i input directly something to a sliderInt (using ctrl+click) then how can i make sure that i change my connected variable only when the value is final (enter was pressed)?
i tried checking for isItemDeactivatedAfterEdit etc. and only updating my variable when needed, but whatever solution i do it either does not work correctly for direct input or it is good for direct input but it does not work at all for changing value by grabbing the slider.

one thing i could not achieve is to set a delay time only after which these tooltips appear.

~~Must be your choice, but idk what you trying to achieve...~~

Added new functions

No problems for me...

@rrraptor does imgui have some kind of 'built-in' soft keyboard?

@SinisterSoft @hgy29 I just read an article here about Text Input for games on Android. It is supported by Google and has C API, so I think we can take a look and have something like "Android Game Development Kit" plugin for android would be great!

hi, with this i can achieve that both drag and textinput only updates when it is finished. but in fact i want drag to update continuously yet textinput should only update when it is finished. i tried many combinations, but i still could not achieve this. (thanks for your patience and help)

indeed, my bad, i messed up my code.

keszegh · July 2021

bug?: ImGui.ColorEditFlags_NoTooltip does not seem to have an effect on colorButton (it works for colorEdit3), i cannot hide the tooltip.

keszegh · July 2021

when using colorEdit3() in the popup i have two colors, current and original.
yet in colorPicker3() i only have current. is there a way to show original also there? (i.e., my colorPicker3 outcome should be identical to the colorEdit3() outcome. thanks

keszegh · July 2021

i thought that a colorButton can automatically be the target of a drag-n-drop operation of a colorEdit3 but it is not the case. is that a bug?
in other words: i can drop a colorEdit3 color on a colorButton but i cannot drop a colotButton color on anything.

You can always check features that you need in ImGui's demo windo, because its written in C++
If it works exactly the same way in LUA then its not a problem from my side.
