  1. Got challenged the other day by trying to scroll large numbers of rows in a listbox. Browsers are very good at scrolling, but when row numbers become large and the scroll context becomes complex, scroll behaviour deteriorates. A simple un-optimised scrolling div is, rule of thumb, able to scroll comfortably up to a couple of hundred rows. Depending on browser and complexity. In the native framework I tweaked that a bit by setting all rows outside the visible viewport to 'display:none'. That extends comfortable scrolling somewhat, say to numbers in the low thousands. A bett
  2. Hi i was wondering if someone could explain the process of enabling scrolling on a form without mapping a TW3ScrollBox over the whole thing, and then mapping the components to ScrollBox.Contents? If that's the easiest method that's fine, it's just a bit tedious rearranging the inheritance of a lot of my project if there is a better method available. For example would i want to add a ScrollController property/object to the form and then expect that to be sufficient?
  3. I am still having a hard time with a Listbox and distinguishing between "touch" to select and item in a listbox on a desktop/laptop browser.....and "touch" to begin scrolling (e.g. on a phone/tablet) Using a basic example listbox with 100 items procedure TForm1.Resize; var i: integer; begin inherited; W3ListBox1.Clear; for i:= 1 to 100 do W3ListBox1.Add('Item ' + inttostr(i)); W3ListBox1.SetBounds(0,0,width,height); end; When a user is using the desktop/laptop browser, I need them to be able to use both mouse and touch (case their monitor is touch) to "scroll"
  4. I need to place a large amount of text that needs to be placed in a control and placed on my form. The text needs to able to be word wrapped and scroll-able. However, I do not want visible scrollbars such as seen in a TW3Memo. Can I use TW3ScrollControl for this? I have no idea how much text will be there, but at the most three large paragraphs. The text will need to word wrap based on the size of the control holding the text. I tried using a TW3Label but it seems it has no wrapping procedure TForm1.InitializeForm; var s: string; i: integer; begin inherited; //
  5. How to hide scrollbars on TW3Memo? Or, how do I display large amounts of text with word wrap, like in the memo? code https://github.com/holmesshanea/smartmobilestudio/tree/master/preZidents test https://rawgit.com/holmesshanea/smartmobilestudio/master/preZidents/www/index.html test in mobile http://ipadpeek.com/ just select the device and orientation (rotation) What I am trying to achieve is display a large amount of text (wordwrapped) and have it display - no matter the device and orientation - and be able to scroll through the text that isn't visible on the disp
  6. using the TW3Scrollbox's Vertical and Horizontal scroll bars work great with the mouse in a browser. Both the bars can be dragged with the mouse, and the arrows at each end can be clicked to move the bars. However, they are not working in my Android Device. Do I have to utilize the Scrollbox's OnGesture or OnTouch events? If so, how do I do so. Btw, the same thing for the TW3Memo control
