[HELP] Update image when selecting row

[..:D&G:..]

Hello guys, I am trying to make a gridlist with items, and when the player clicks a row with lets say "Item1", the image from the left size of the gridlist, is updated with a value from the table:

local items = { 
       {"Infernus", 5, "vehicles/infernus.png"}, 
       {"Bullet", 3, "vehicles/bullet.png"}, 
} 
for i, v in ipairs(items) do 
            local row = guiGridListAddRow(donItemsList) 
            guiGridListSetItemText(donItemsList, row, donItemsName, v[1], false, false) 
            guiGridListSetItemText(donItemsList, row, donItemsPrice, v[2]..".00 €", false, false) 
        end 

I don't know how to update the picture and and to get the picture of the selected item...

Thanks.

guiGridListGetSelectedItem 

[..:D&G:..]

I tried this but it doesn't destroy the default picture(cover picture) nor create a new one...

for i, v in ipairs(items) do 
            local row = guiGridListAddRow(donItemsList) 
            guiGridListSetItemText(donBunuriList, row, donItemsName, v[1], false, false) 
            guiGridListSetItemText(donBunuriList, row, donItemsPret, v[2]..".00 €", false, false) 
             
            local item = guiGridListGetSelectedItem (donItemsList) 
            local donItem = guiGridListGetItemText(donItemsList, item, 1) 
            destroyElement(donItemsPic) 
            donItemsPic = guiCreateStaticImage(291, 144, 219, 206, "images/"..donBun..".png", false, donItemsMain)  
        end

use

guiStaticImageLoadImage() 

[..:D&G:..]

I tried this:

local item = guiGridListGetSelectedItem (donItemsList) 
             
            guiStaticImageLoadImage(donItemPic, item.v[3]) 

But it doesn't get the "item" and the text, picture and only 1 item is displayed in the gridlist..

[..:D&G:..]

I got to a point where, when I click an item from the gridlist, it gets the 8th item only, and when I click another item, it doesn't change...

addEventHandler ( "onClientGUIClick", getRootElement(), function (button, state) 
            if(button == "left") then 
                if(donBunuriPic) then 
                    destroyElement(donBunuriPic) 
                    donBunuriPic = nil 
                end 
                if(source == donBunuriList) then 
                    if(guiGetVisible(donBunuriMain)) then            
                        local row, column = nil  
                        local row_temp, column_temp = guiGridListGetSelectedItem ( source )  
                        if((row == nil) and (row_temp)) then 
                            row = row_temp 
                            column = column_temp 
                                donBunuriPic = guiCreateStaticImage(291, 144, 219, 206, v[3], false, donBunuriMain)   
                            end 
                        end 
                    end 
                end 
            end 
        end)

Use this, and make sure that I placed your image path correctly!...

function selectedImage (button) 
    if (button == "left" ) then 
        if (source == donBunuriList) then 
            currentImage = guiGridListGetItemText ( donBunuriList, guiGridListGetSelectedItem ( donBunuriList ), 1 ) 
            if ( donBunuriPic ) then 
                if guiStaticImageLoadImage ( donBunuriPic, ..yourPreferredImage.. ) == false then 
                    guiStaticImageLoadImage ( donBunuriPic, ..yourimage.. ) 
                end 
            else 
                currentImage = guiCreateStaticImage(291, 144, 219, 206, v[3], false, donBunuriMain) 
            end 
        end 
    end 
addEventHandler( "onClientGUIClick", donBunuriList, selectedImage ) 
end

        end 
    end

end 

How is this even supposed to work? "v[3]" will be nill and the 4th if makes no sense, anyway it doesn't work, but thanks for trying to help me.

thats what i mentioned on my last post, that i dont know your image path nor image list or anything about the images. So you have to edit the code and do it your self if not working..

[..:D&G:..]

This is the default picture, which shows when no item is selected:

donBunuriPic = guiCreateStaticImage(291, 144, 219, 206, "images/default.png", false, donBunuriMain) 

And the image that needs to show when an item is selected, is for each item in the table:

local bunuri = { 
--Masini 
    {"Infernus", 5, "images/vehicles/infernus.png"}, 
    {"Bullet", 5, "images/vehicles/bullet.png"}, 
    {"Turismo", 5, "images/vehicles/turismo.png"}, 
    {"Super GT", 4, "images/vehicles/supergt.png"}, 
    {"Banshee", 4, "images/vehicles/banshee.png"}, 
    {"Cheetah", 4, "images/vehicles/cheetah.png"}, 
    {"Hotring Racer", 3, "images/vehicles/hotring.png"}, 
    {"Hotring Racer 2", 3, "images/vehicles/hotrina.png"}, 
    {"Hotring Racer 3", 3, "images/vehicles/hotrinb.png"}, 
}

function selectedImage() 
    local row = guiGridListGetSelectedItem(donBunuriList) 
    local currentImage = tostring(guiGridListGetItemText(donBunuriList,row,1)) 
    if(currentImage == "") or (currentImage == " ") then 
        guiStaticImageLoadImage(donItemsPic,"images/default.png") 
    else 
        if(fileExists("images/"..string.lower(currentImage)..".png")) then 
            guiStaticImageLoadImage(donItemsPic,"images/"..string.lower(currentImage)..".png") 
        else 
            guiStaticImageLoadImage(donItemsPic,"images/default.png") 
        end 
    end 
end 
  
-- add your event handler onClientGUIClick 

[..:D&G:..]

Doesn't work... Maybe the eventHandler is wrong?

addEventHandler ( "onClientGUIClick", donItemsList, selectedImage ) 

[Walid]

lol what's your gridList name

i think it's donItemsList right.

[..:D&G:..]

It is donItemsList
