* Remove quality evaluation in test stringEskil Abrahamsen Blomfeldt2020-06-102-2/+2
| | | | | | | | | | | | | It is not the test's place to evaluate the quality of the outline shader (which also looks perfectly fine unless you don't really like outlined text). And it looks unprofessional to use rude words to describe our code in manual tests. Strings in lancelot tests are also inefficient ways of reporting and tracking bugs if that was the intended use of this.

* Fix: NativeRendering text for non-integer screen scalingEirik Aavitsland2019-11-181-0/+37
| | | | | | | | | | | | | | Commit 6e883c53 introduced snapping to pixel grid for non-integer device pixel ratios. But the snapping also modified the w element of the coord vector, which resulted in mangled and offset rendering. As a driveby, add the dpr snapping also to the outlinetext shader, as it improves rendering quality.

| * Fix possible crash with top/bottom aligned imagesEskil Abrahamsen Blomfeldt2019-07-301-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An image inside at the end of a text block which did not start at text position 0 would resolve to an invalid QTextLine, since we passed the document position to lineForTextPosition(), which expects the relative block position. If the image was aligned to top or bottom, so that the extracted QTextLine was actually accessed, this would cause a crash. [ChangeLog][QtQuick][Text] Fixed a bug where aligning an image to "top" or "bottom" could cause a crash under certain circumstances.

| | | | | | | | | | | | | | | | | In the code that converts text layouts to subtrees in the scene graph specifically for TextEdit, there was a cutoff to treat text tables as single nodes in the graph (for simplicity). However, this breaks selections, since the ranges spanned by each cell will be interpreted as overlapping, messing up the selection merging logic. We need the same approach here as for any other text frame where we check frame boundaries. [ChangeLog][TextEdit] Fixed issues with selections that spanned several cells in a table.

* Fix selecting single character in middle of stringEskil Abrahamsen Blomfeldt2015-08-031-0/+13
| | | | | | | | | | | | | | | The fix for QTBUG-46829 revealed a bug in the code to handle selecting part of ligatures. The ranges were assumed to be [start, end], while they are in fact [start, end>. This would cause the engine to assume the previous node overlapped completely with the selected node and that the node had thus already been added to the graph. Due to the bug in QTBUG-46829, this accidentally worked before, but when that bug was fixed, this bug appeared.

* Fix disappearing selection spanning different scriptsEskil Abrahamsen Blomfeldt2015-08-031-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the way itemization is currently done in Qt, Cyrillic text (and other writing systems) separated by spaces will become separate items because the spaces are itemized as Script_Common. In the Scenegraph's text node engine, we should merge these items into a single node as long as the same font is used for all the text. But a bug in the engine caused this to fail when the text was selected. The symptom of this was that in some rare cases one of the items would vanish if it were in the middle of a selection. In order to support the bearing of selected text leaning outside the selection rect, I previously added a hack which would add all selected text as unselected text as well in b0783c21fb54b939f07ddf5658cc51113b8014e6. This was an awkward way of doing it and caused said regression. A less intrusive way is just to add the text to the scene graph twice, as this does not interfere with the logic needed to support selecting part of ligatures nor the engine's ability to merge nodes correctly. [ChangeLog][Text] Fixed regression with selections spanning different scripts.

* Fix TextEdit when vertical alignment != AlignTopEskil Abrahamsen Blomfeldt2015-04-091-0/+21
| | | | | | | | | | | | | | | | | | | | | | | When the TextEdit's alignment was either AlignBottom or AlignVCenter, several things would be broken: First of all the position of all non-dirty nodes would not be updated, so if you e.g. added text to the end of the document, it would overlap with the previously added text. Also, the frame decorations were always aligned to the top, since the basePosition was not accounted for in the node for this. The fix is to translate the root node to the base position instead of baking this into the position of the text nodes. This also automatically fixes frame decorations since it's already aligned to the top of the root node. [ChangeLog][TextEdit] Fixed issues with using other vertical alignments than AlignTop.

* Fix selection of text with negative right bearingEskil Abrahamsen Blomfeldt2014-09-026-0/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Selecting text with a negative right bearing (like italic text) would cause clipping to occur at the edges of the characters. The algorithm for drawing text and text selection tried to divide the text into two: 1. Selected text, and 2. Unselected text. However, the selected text might be drawn outside the selection rect when it has a negative right bearing. Similarly, unselected text before the selection might overlap with the selection rect when it has a negative right bearing, or unselected text after the selection might overlap if it has a negative left bearing. See added test textinput_italic_selected.qml for an example. To rectify this, we do drawing of selected text like this: 1. Draw all text with unselected color 2. Draw selection rects 3. Draw the following in the selection text color and clipped to the selection rect: A. The selected text B. The unselected text right before the selection C. The unselected text right after the selection To avoid drawing the same text twice for extra boldness, we check if 3B or 3C actually contain 3A, in which case we skip 3A. [ChangeLog][Text] Fixed clipping when selecting text with negative right bearing.
