| [02:15:33] | jpabq: | I figured out the upside-down text. In didn't occur to me that a default constructed QImage would not be blank. For some reason, when drawing onto a QImage with random garbage in it, the result can be a mirror of what was intended. |
| [04:58:43] | jpabq: | How important is it to keep support for a blinking cursor in a textedit? QTextLayout has built in support for a cursor, but it does not blink, and the only control over the shape, is how wide it is. If we want to continue allowing for a blinking cursor of an arbitrary shape, then mythui will have to draw it, itself — like it does now. |

| [10:22:06] | stuartm: | jpabq: it's a small sacrifice I guess |
| [10:28:21] | stuartm: | that said, QTextLayout's cursor support isn't much better than drawing the cursor ourself, you have to specify the position which means you still need to calculate that position |
| [10:29:09] | stuartm: | since calculating the position is as hard as it gets, we gain nothing by using the QT cursor that I can see |

| [14:55:04] | jpabq: | stuartm, the position you provide to QTextLayout is character based, not pixels, so is pretty easy. That being said, I am leaning towards keeping the cursor drawing in mythuitextedit, since you have already done all the work to make it blink, etc. |
| [14:56:31] | stuartm: | jpabq: one of the arguments to drawCursor() is a QPoint? |
| [14:56:58] | jpabq: | That is just an offset, in case the origin is not 0,0 |
| [14:57:10] | stuartm: | jpabq: the blink is nothing fancy, just a timer toggling between the hidden/visible states |
| [14:57:27] | stuartm: | jpabq: ahh, ok that wasn't clear to me from the docs |
| [14:57:44] | jpabq: | Me neither. I had to experiment with it. |
| [15:00:12] | jpabq: | Off to work... I wont be able to tinker much more with this, until the weekend, but it does look promising. |
| [15:00:38] | stuartm: | cool |
