I have spent a bit of time trying to figure this out and I'm not getting too far.
I went back to 2017 and added a button for a web skin that worked exactly as you want. It opened my site in the topic area.
What appears to be the same method in 2019 doesn't work at all. That made me wonder if you are using 2019 Classic or 2019 New UI as asked earlier?
Please clarify what you are using and exactly how you are getting it to open the target, albeit not as you want.
I'm using the new 2019 UI. The steps I've taken are:
1. Edit the Azure_Blue Skin
2.Under 'Custom Buttons' add new button and icon
3. Under 'Link' I add the url
Interesting. That's exactly what I did and it would not open anything. I added http://www.grainge.org and nothing happens when I click the button. I'll try some more tomorrow.
Selecting the appropriate button and then adding the URL in ‘GENERAL’ ==> ‘Link’ is working fine and opens the given URL in new tab.
Please follow the below steps to open the desired URL in the same window as the topic:
I tried it and what that does is override the whole Robohelp window thus requiring the user to click the back button to get back to the online manual. The goal is for the target to just be the topic window and not the entire webpage. Painting the picture: I want a button on the toolbar (not the table of contents) that will open a webpage in the topic window allowing the user to access a webpage while still in the Robohelp environment where the skin remains the same with the toolbar on the top and the table of contents on the left. We have current manuals that were created in previous versions that have this option and I was able to open up Robohelp Classic to see how it was done. The 'button wizard' automatically programmed the button to open the webpage in the topic window.
I believe that your problem could be solved by changing the "_self" to "rh_default_topic_frame_name".
I was adding the link exactly as you describe and it failed every time. Then I tried another site and it worked. I went back to the first site and that then worked!
I tried Sudhanshu1996Monga's script and got the same as you and understand that is not what you want. I have asked Adobe if there is a solution for this version and will post back with whatever they advise.
Maria - The revised script does work but be aware some web sites do not allow their site to be displayed in a frame. In Firefox you would then get a white area but Edge gives the reason.
I hit this when I tried www.adobe.com. With my own site it worked fine.
YES!!!! It works. Thank you soooooo much Peter and Sudhanshu1996Monga. At first try it opened the link and it did open the webpage in the topic window but it also opened in a new tab. After removing the web address under 'Link' and clearing chaches it only opened up in the Robohelp program. Thanks again, mystery solved, feeling triumphant 😄
