3 pictures added with Table menu add an image file. Table created:
| Code: | | local picturestbl = { [1] = 'pict-1.gif', [2] = 'pict-2.gif', [3] = 'pict-3.gif' } |
How to change pictures with 2 buttons in the CEImage1? If CEButton1 is clicked, then show pict-1.gif, if CEButton2 is clicked, then show pict-2.gif.
How to change pictures with 2 buttons in the UDF1 form with same way?
Can you make a .CT file for example? |
CE still does not support .gif.
You should create a gif with the help of the following code.
How to:
1) .CT "Add File" (create gifi: split into .png and upload to CT)
2) Set picture names: (Example: There are 9 pictures ..
Names: frame_001 .. frame_002 .. frame_003 .. frame_009 etc. )
3) Process the image numbers in the code: For gif1: "for i = 1,9 do"
Example for gif2: "for i = 10,18 do"
4) Give ButtonClick approvals: "gif1.image.stretch = false
gif1.image.Visible = false "or gif2 etc.
