| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a dialog was parented on a native child widget, its window handle was used as a transient parent. This confused QPlatformWindow::initialGeometry() among other things. Use top level window as is in Qt 4.

| * Fix fallbacks for adapted common scriptEskil Abrahamsen Blomfeldt2014-07-103-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the platform plugin gives us specific fallbacks for a specific script, we need to respect this, and load the correct font family regardless of which writing systems it supports. This is especially important since the common script is adapted to match surrounding, proper scripts, so characters such as digits next to e.g. Hebrew text will be marked as Hebrew. On stock Android, there is a single Hebrew font, and this would previously be put in all fallback slots for Hebrew regardless of what fallback fonts were dictated by the platform plugin. Since this font does not support the digits, they would show up as boxes. [ChangeLog][Android] Fixed common characters like digits and punctuation showing as boxes when positioned next to non-latin scripts.

| | | | | | | | | | | | | | | | | | | | | | | | Since we have no interest in fixing HB-old to properly support surrogates, here is a simple workaround for the case when surrogate parts gets treated like two separate glyphs in log_clusters but a single character. And since it's a known issue that HB-old doesn't really support surrogates, it's better to draw some garbage/boxes rather than to assert, IMO.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At some point since Qt 4.8, the nbsp character has acquired the whitespace attribute, causing it to be treated exactly like an ordinary space. To account for this, we add an extra check in the layout code to avoid breaking on non-breaking spaces even if they have the whiteSpace flag set. This is a temporary fix for the regression. The line breaking algorithm needs to be refactored and support Unicode tr14 properly, which it currently doesn't. [ChangeLog][Text] Fixed lines breaking on non-breaking spaces.

The problem was that the GL version was wrong in the first place -- buffer textures are natively supported since OpenGL 3.0, not 4.3. 4.3 introduced support for buffer texture ranges, i.e. ARB_texture_buffer_range; however it's pointless to take the highest requirement, especially considering that so far QOpenGLTexture doesn't wrap glTexBuffer(Range) in any way. In the future, if QOpenGLTexture will also wrap glTexBuffer, then we will also be able to introduce a different feature flag for testing buffer texture ranges.

| | | | * Handle invalid sample counts gracefully in FBOsLaszlo Agocs2014-06-181-0/+1

This is common when setting up framebuffer formats from a QSurfaceFormat where the default, unset value is indicated by a value of -1. This broke QQuickWidget which was unaware of this limitation of QOpenGLFramebufferObject and was passing format.samples() as the sample count without making sure it is 0 or higher.
