Remove item from the autoload of TUniDateTimePicker
marcos.digirotas replied to marcos.digirotas's topic in General
I don't know if it is the best way, but I reach my goal by adding the code: function afterCreate(sender) { sender.store.data.items[0].data.disp = '00:01'; } -
Remove item from the autoload of TUniDateTimePicker
marcos.digirotas replied to marcos.digirotas's topic in General
Hello Sherzod! Actually I would like to keep the interval in 15 minutes, but I would just like to remove the "00:00" time, or at least change this specific time to 00:01 and keep the others with 15 minutes intervals, example: 00:01, 00:15 , 00:30 ... -
Добрый день, Какую сборку UniGUI Вы используете?

Dear UniGUI team: I would be pleased if you could replay following questions because I just upgrade to use this feature (Hyperserver) and I need to be sure about some basics: Hyperserver can create, recycle and destroy nodes, so it can move active sessions from one node to another. The sessionId actually has something like the node where it is created at the beginning of the string, has it?. So, when a session is moved from one node to another, it will maintain its whole session Id indicating on which node it was created, is this true? Is there a way for a session or its application to know on which node is running now?. This feature would be desirable, in addition to events in UniMainModule to signal leaving and entering node. This could help a lot when globally managing sessions. When Hyperserver moves sessions from one node to another, does it move each session individually, grouping them or all of them at the same time, in a kind of transaction? If the session to be moved has thrown a thread, will the thread be accessed correctly after the movement? Assuming that the Hyperserver installer was installed once in the deployed machine and restarted, when upgrading the version of unigui, is it necessary to use again the hyperserver installer on deployed machine or it is enough distributing the exe or the dll of the hyperserver? Thank you in advance, Regards,

OK, I'm new here, having owned UniGui for years but first using it now. I run the blocking demo and the ShowModal is blocking, waiting for the ModalResult When I implement what I think is the same thing in my code, it doesn't block. MR1 := dlgNewGroups.ShowModal; <== My code. What's the blocking demo doing that is special that I'm somehow missing? Thanks

I am developing a simple card game. Naturally, it needs to involve a complete set of 52 playing card images. I have a set of .PNG files. If necessary, I can get .BMP files or some other kind. The problem is... How do I go about bringing these images into my uniGUI project? There is no TUniImage. I tried to make use of TUniImageList but couldn’t figure out how. At design time, this control doesn’t seem to let you do anything with it. Searched for help on the web but couldn’t find any. Another approach might be to put the images into the project's resource file, but how do I make use of them from there? Any ideas would be much appreciated.
