TL;DR: TextEdit paints highlighted text only when I click on it. Nothing helps
I have a ListView with a QAbstractListModel model with string properties. Those string properties are being spellchecked and QSyntaxHighlighter is used to show spell errors. I create QSyntaxHighlighter descendant in Component.onCompleted of TextEdit. I double-checked highlighting get's executed with correct spell errors and setFormat() of Highlighter is executed with correct positions. The problem is that it draws text in red (invalidates) only when I click on the TextEdit itself.
TextEdit lives in a Flickable (to track cursor) and Flickable lives in a Rectangle (to have nice background and border). Binding to some signals and calling update() of TextEdit does not help.
After spellcheck finishes, I emit rehighlight() signal of created SyntaxHighlighter.
Rectangle {
id: descriptionRect
height: 30
border.width: descriptionTextInput.activeFocus ? 1 : 0
clip: true
Flickable {
id: descriptionFlick
contentWidth: descriptionTextInput.paintedWidth
contentHeight: descriptionTextInput.paintedHeight
anchors.fill: parent
interactive: false
flickableDirection: Flickable.HorizontalFlick
height: 30
clip: true
focus: false
function ensureVisible(r) {
if (contentX >= r.x)
contentX = r.x;
else if (contentX+width <= r.x+r.width)
contentX = r.x+r.width-width;
}
TextEdit {
id: descriptionTextInput
width: descriptionFlick.width
height: descriptionFlick.height
text: description
onTextChanged: model.editdescription = text
Component.onCompleted: {
globalModel.initDescriptionHighlighting(index, descriptionTextInput.textDocument)
}
onCursorRectangleChanged: descriptionFlick.ensureVisible(cursorRectangle)
}
}
}
Rectangle {
id: descriptionRect
height: 30
border.width: descriptionTextInput.activeFocus ? 1 : 0
clip: true
Flickable {
id: descriptionFlick
contentWidth: descriptionTextInput.paintedWidth
contentHeight: descriptionTextInput.paintedHeight
anchors.fill: parent
interactive: false
flickableDirection: Flickable.HorizontalFlick
height: 30
clip: true
focus: false
function ensureVisible(r) {
if (contentX >= r.x)
contentX = r.x;
else if (contentX+width <= r.x+r.width)
contentX = r.x+r.width-width;
}
TextEdit {
id: descriptionTextInput
width: descriptionFlick.width
height: descriptionFlick.height
text: description
onTextChanged: model.editdescription = text
Component.onCompleted: {
globalModel.initDescriptionHighlighting(index, descriptionTextInput.textDocument)
}
onCursorRectangleChanged: descriptionFlick.ensureVisible(cursorRectangle)
}
}
}
To copy to clipboard, switch view to plain text mode
Any ideas how I can solve this?
