I am trying to add a new button to the WinEdt 9.1 toolbar menu. I have already put in place the command in the MainMenu.ini file:
ITEM="Matlab" CAPTION="Matlab" IMAGE="Matlab" MACRO="Run('"C:\Program Files\MATLAB\R2014b\bin\matlab.exe" "%N%T""','%P','',100,0,'','','',111);"`
and also updated the Toolbar.ini file. However, in the the toolbar, the place where the icon should show up, shows up blank. The new icon is a 16x16 .png file in the "...\WinEdt Team\WinEdt9\Bitmaps\Images" folder. If I hover my mouse around the place where the icon should show up on the toolbar, I do see the caption ("Matlab") and a raised blank box. I know in the past WinEdt version (version 5) that you had to modify a WinEdt.btn file and add a line with your new icon, but I do not see that file anymore. Is there somewhere else you have to specify your newly added icon?
